OEIS Sequences

a(n) = 961·n² - 2·n. A158410

a(n) = ∑_k=1..n F(n mod k) where F = A000045, the Fibonacci numbers. A198259

For n > 1 the sum of t := floor(n/2) + 1 consecutive previous terms, the leading t terms when n is even, the immediately-preceding t terms when n is odd; a(0) = 0, a(1) = 1. A238834

Take apart the sides of each of the integer-sided scalene triangles with perimeter n (at their vertices) and rearrange them orthogonally in 3-space so that their endpoints coincide at a single point. a(n) is the total volume of all rectangular prisms enclosed in this way. A308234
