%N Partial sums of A246031.

%C Total number of cubic ON cells after n generations in a three-dimensional structure in which A246031(n) gives the number of cubic ON cells in the n-th cubic layer of the structure. A cubic ON cell remains ON forever. The structure looks like an irregular cube (or hexahedron).
