Battle of the Iron Triangle ending a bitter four-month struggle. Following the withdrawal from Base 82 COSVN organized a new corps headquarters in the Tay Ninh- Binh Long region and designated it the 301st Corps. This corps would soon direct the combat operations of the 7th and 9th NVA Divisions, separate regiments, and additional formations already en route from North Vietnam.

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
