%N Eigensequence of triangle A038208

%F Given triangle A038208 as an infinite lower triangular matrix: [1; 2,2;

%F 4,8,4; 8,24,24,8;...], shift the triangle down one row, inserting "1"

%F at (0,0) = triangle Q. Then Lim:_{n->inf.} Q^n generates a one-column

%F vector [1, 1, 4, 28, 352,...] such that A038208 * the vector = [1, 4, 28,...].

%Y A038208
