Comments

a(n) is also the area of one of the faces of the rectangular cuboid which is a three-dimensional version of the shell model of partitions of n. The areas of the other faces are A008606(n)=24*n and A066186(n)=n*p(n), where p(n) is the number of partitions of n. See A135010 for more information.

Examples

			The number of partitions of 6 is p(6) = A000041(6) = 11, so a(6) = 24*11 = 264.
