The number of rectangles (orthogonal or not) with corners on an n X n grid of points. A85582

Consider the Diophantine equation x³ + y³ = z³ - 1 (x < y < z) or 'Fermat near misses'. The values of z (see A050787) are arranged in monotonically increasing order. Sequence gives values of y. A50789

a(n) = 100·n² - n. A157659

a(n) = 400·n² - 2·n. A158316
