• Number of inequivalent n-colorings of the 5D hypercube under the set of geometric transformations generated by all possible compositions of the 5 main reflections and the 10 main rotations and their inverses, in any order, with repetition of these geometric transformations allowed.at n=1A129347
• Erroneous version of A000616.at n=5A261014
• Array read by descending antidiagonals: A(n,k) is the number of unoriented colorings of the facets of a regular n-dimensional orthoplex using up to k colors.at n=19A325013
• Array read by downward antidiagonals: A(n,k) is the number of nonequivalent 2-colorings of the cells of an n-dimensional hypercube with edges k cells long under action of symmetry.at n=33A361870
