David Robinson (basketball) Final season and second championship What did David Robinson do Robinson announced he would retire from basketball after the 2002-03 season. Did he win a championship On June 15, 2003, in the finale of Robinson's career, the Spurs won another NBA title with an 88-77 victory over the New Jersey Nets Did they get a ring I don't know. Are there any other interesting aspects about this article? Robinson averaged 21.1 points per game, 10.7 rebounds per game, 3 blocks per game, and 2.5 assists per game over 987 games in his NBA career. Did he receive any awards? he is one of only a very small group of players to have scored over 20,000 career points in the NBA, What team did he play for the Spurs How many years did he play I don't know. Did he do anything else important being one of only four players to have recorded a quadruple-double

Robinson announced he would retire from basketball after the 2002-03 season.  On June 15, 2003, in the finale of Robinson's career, the Spurs won another NBA title with an 88-77 victory over the New Jersey Nets in Game 6 of the 2003 NBA Finals. Turning back the clock, Robinson scored 13 points and grabbed 17 rebounds in his final game for the Spurs. He and the year's regular season and NBA Finals MVP Tim Duncan shared Sports Illustrated magazine's 2003 Sportsmen of the Year award.  Robinson averaged 21.1 points per game, 10.7 rebounds per game, 3 blocks per game, and 2.5 assists per game over 987 games in his NBA career. Also, he is one of only a very small group of players to have scored over 20,000 career points in the NBA, as well as being one of only four players to have recorded a quadruple-double (with 34 points, 10 rebounds, 10 assists, and 10 blocks against the Detroit Pistons on February 17, 1994).  He is also one of only six players to record 70 or more points in a single game with 71 points against the Los Angeles Clippers on April 24, 1994. Only Elgin Baylor (71 points), Wilt Chamberlain (70, 72, 73 twice, 78, 100 points), David Thompson (73 points), Devin Booker (70 points), and Kobe Bryant (81 points) have scored 70 or more points in a single game.  Robinson is also noteworthy for his harmonious relationship with Tim Duncan. Sportswriter Chris Sheridan noted that it was rare for someone like Robinson to have welcomed and mentored Duncan as willingly as he did. CANNOTANSWER

Place of birth missing (living people) Shannon's Mob is an Australian TV series about an Australian intelligence agency. It was the last TV series from Fauna Productions, who were responsible for Skippy the Bush Kangaroo among others.

Synopsis
FIASCO (The Federal Intelligence and Security Organisation) is a top-secret department whose existence was known only to a few and was answerable only to the Prime Minister.  Under the control of one time Scotland Yard cop Dave Shannon, the main characters were agents Andrew Blake (Robin Ramsay) and Michael Jamieson (Frank Gallacher) who often worked undercover.

Production
Production of the series took place from October 1973 to May 1974, mostly in and around Sydney.

Reception
The series did not screen until October 1975. It was not a rating success and did not sell well overseas. TV critic Don Storey wrote that "not only was Shannon's Mob Fauna's least successful production, it was one of the least remembered series of Australian television's first twenty years."

1976 Australian television series endings A Pythagorean quadruple is a tuple of integers , , , and , such that . They are solutions of a Diophantine equation and often only positive integer values are considered. However, to provide a more complete geometric interpretation, the integer values can be allowed to be negative and zero (thus allowing Pythagorean triples to be included) with the only condition being that . In this setting, a Pythagorean quadruple  defines a cuboid with integer side lengths , , and , whose space diagonal has integer length ; with this interpretation, Pythagorean quadruples are thus also called Pythagorean boxes. In this article we will assume, unless otherwise stated, that the values of a Pythagorean quadruple are all positive integers.

Parametrization of primitive quadruples 
A Pythagorean quadruple is called primitive if the greatest common divisor of its entries is 1.  Every Pythagorean quadruple is an integer multiple of a primitive quadruple.  The set of primitive Pythagorean quadruples for which  is odd can be generated by the formulas

where , , ,  are non-negative integers with greatest common divisor 1 such that  is odd. Thus, all primitive Pythagorean quadruples are characterized by the identity

Alternate parametrization
All Pythagorean quadruples (including non-primitives, and with repetition, though , , and  do not appear in all possible orders) can be generated from two positive integers  and  as follows:

If  and  have different parity, let  be any factor of  such that .  Then  and .  Note that .

A similar method exists for generating all Pythagorean quadruples for which  and  are both even. Let  and  and let  be a factor of  such that . Then  and . This method generates all Pythagorean quadruples exactly once each when  and  run through all pairs of natural numbers and  runs through all permissible values for each pair.

No such method exists if both  and  are odd, in which case no solutions exist as can be seen by the parametrization in the previous section.

Properties
The largest number that always divides the product  is 12. The quadruple with the minimal product is (1, 2, 2, 3).

Relationship with quaternions and rational orthogonal matrices
A primitive Pythagorean quadruple  parametrized by  corresponds to the first column of the matrix representation  of conjugation  by the Hurwitz quaternion  restricted to the subspace of quaternions spanned by , , , which is given by

where the columns are pairwise orthogonal and each has norm . Furthermore, we have that  belongs to the orthogonal group , and, in fact, all 3 × 3 orthogonal matrices with rational coefficients arise in this manner.

Primitive Pythagorean quadruples with small norm
There are 31 primitive Pythagorean quadruples in which all entries are less than 30.
