Triangle T, read by rows, where T(n,k) = [Tⁿ](n-k-1,0); i.e., where row n of T equals the initial n terms of column 0 in matrix power Tⁿ, reversed and with an appended '1', for n>0, with T(0,0)=1. A167015

Column 0 of triangle T=A167015: a(n) = T(n,0) = [Tⁿ](n-1,0) for n>0 with a(0)=1. A167016

a(0) = 1, and for n > 0, a(n) = A019565(∑_i=0..n-1 a(i)), where A019565 is the base-2 exp-function. A376406
