• Triangle T, read by rows, where T(n,k) = [T^n](n-k-1,0); i.e., where row n of T equals the initial n terms of column 0 in matrix power T^n, reversed and with an appended '1', for n>0, with T(0,0)=1.at n=28A167015
• Column 0 of triangle T=A167015: a(n) = T(n,0) = [T^n](n-1,0) for n>0 with a(0)=1.at n=7A167016
