%N A346531 a(n) is the number of edges of the polycube called "tower" described in A221529 where n is the longest side of its base.
%C A346531 The tower is a geometric object associated to all partitions of n.
%C A346531 The height of the tower equals A000041(n-1).
%F A346531 a(n) = A346530(n) + A346532(n) - 2 (Euler's formula).
%e A346531 For n = 1 the tower is a cube, and a cube has 12 edges, so a(1) = 12.
