%N Triangle A(k,n) = (2)^k+2^n read by rows.
%C The flattened sequence a(A000217(k)+j)=A(k,j) obeys a(n+1)2a(n)= 5, 2, 5, 4, 4, 23, 8, 8, 8, 17, 16, 16, 16, 16, 95, ..., which is a dispersion of 2, 4, 4, 8, 8, 8, ... (a signed version of A140513) with 5, 5, 23, 17, 95, 65,... The latter sequence is A(k,0)2*A(k1,k1), an alternation of the negative of A140529 with each second element of A000051.
%F A(k,n) = A000079(n)+A122803(k).
%e Rows starting at k=0: (2), (1,0); (5, 6, 8); (7,6,4,0); (17,18,20,24,32);...
