Numbers congruent to 3 in the structure (or curve) of A211000. A211002

Triangle, read by rows, where row n forms a polynomial in y=3·k that generates diagonal n as k=0,1,2,... for n>=0; thus T(n,k) = ∑_j=0..n-k T(n-k,j)*(3·k)^j, with T(n,0)=T(n,n)=1. A113716

a(n) = [xⁿ] ∏_k=1..n (1+x^k)² / x^k. A258797

Column 2 of triangle A113716, in which row n forms a polynomial in y=3·k that generates diagonal n as k=0,1,2,... for n>=0. A113718

a(n) is the index of the first occurrence of n in A166006. A278737
