Year-end appeal: Please make a donation to the OEIS Foundation to support ongoing development and maintenance of the OEIS. We are now in our 59th year, we have over 358,000 sequences, and we’ve crossed 10,300 citations (which often say “discovered thanks to the OEIS”).

COMMENTS

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).
