Iron Triangle (Vietnam) Iron Triangle (Vietnam) The Iron Triangle (Vietnamese:"Tam Giác Sắt") was a area in the Bình Dương Province of Vietnam, so named due to it being a stronghold of Viet Minh activity during the war. The region was under control of the Viet Minh throughout the French war in Vietnam and continued to be so throughout the phase of American involvement in the Vietnam War, despite concerted efforts on the part of US and South Vietnamese forces to destabilize the region as a power base for their enemy, the communist North Vietnamese–sponsored and–directed South Vietnamese insurgent movement, the National Liberation Front
Lozanić's triangle numbers "l"(8, "n") (), then alkane numbers "l"(9, "n") (), then "l"(10, "n") (), "l"(11, "n") (), "l"(12, "n") (), etc. The sum of the "n"th row of Lozanić's triangle is formula_1 ( lists the first thirty values or so). The sums of the diagonals of Lozanić's triangle intermix formula_2 with formula_3 (where "F" is the "x"th Fibonacci number). As expected, laying Pascal's triangle over Lozanić's triangle and subtracting yields a triangle with the outer diagonals consisting of zeroes (, or for a version without the zeroes). This particular difference triangle has applications in the chemical study of catacondensed polygonal
