%N A160756 Triangle by rows, infinite lower triangular Toeplitz matrix with A078008 
               in every column convolved with A001333.
%C A160756 Row sums = A001333: (1, 1, 3, 7, 17, 41,...). Sum of n-th row terms = 
               rightmost term of next row.
%F A160756 Let M = an infinite lower triangular Toeplitz matrix with A078008 (1, 
               0, 2, 2, 6, 10, 22, 42, 86, 170,...). Let Q = the eigensequence of 
               that triangle prefaced with a 1: (1, 1, 1, 3, 7, 17,...) where A001333 
               = (1, 1, 3, 7, 17,...). The triangle = M * Q.
