First differences of number of active (ON, black) cells in n-th stage of growth of two-dimensional cellular automaton defined by "Rule 361", based on the 5-celled von Neumann neighborhood. A271417

Square array A(n,k), n >= 0, k >= 0, read by antidiagonals, where column k is the expansion of e.g.f.: exp(-∑_j>=1 sigma_k(j) * x^j). A294951

A symmetrical triangle sequence based on:q=1/12;t(n,m,q)=12*(Binomial[n, m]*(1 - q) + (((n + m + 1)!/((n + 1)!* m!)) + ((2·n - m + 1)!/((n + 1)!*(n - m)!)))*q). A174948

Numbers that are the sum of 2 positive 5th powers. A3347
