• a(n) = 961*n^2 - 2*n.at n=6A158410
• a(n) = Sum_{k=1..n} F(n mod k) where F = A000045, the Fibonacci numbers.at n=45A198259
• 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.at n=29A238834
• 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.at n=38A308234
