60 (number) geometry, it is the number of seconds in a minute, and the number of minutes in a degree. In normal space, the three interior angles of an equilateral triangle each measure 60 degrees, adding up to 180 degrees. Because it is divisible by the sum of its digits in base 10, it is a Harshad number. A number system with base 60 is called sexagesimal (the original meaning of "sexagesimal" is sixtieth). It is the smallest positive integer that is written with only the smallest and the largest digit of base 2 (binary), base 3 (ternary) and base 4 (quaternary).
Sierpinski triangle converge on the Sierpinski triangle. This is what is happening with the triangle above, but any other set would suffice. If one takes a point and applies each of the transformations "d", "d", and "d" to it randomly, the resulting points will be dense in the Sierpinski triangle, so the following algorithm will again generate arbitrarily close approximations to it: Start by labeling p, p and p as the corners of the Sierpinski triangle, and a random point v. Set , where "r" is a random number 1, 2 or 3. Draw the points v to v. If the first
