• Numbers k such that 2k + 1 divides 2^k + k^2.at n=4A327636
• Irregular table read by rows: Take a triangle with Pythagorean triple leg lengths with all diagonals drawn, as in A332978. Then T(n,k) = number of k-sided polygons in that figure for k >= 3 where the legs are divided into unit length parts.at n=33A333135
