%N Triangle, row sums = Fibonacci numbers in two ways.
%C n-th row sum of signed terms = Fn; n-th row sum of unsigned terms = F(2n-3).
%F Diagonalize the inverse binomial transform of the Fibonacci sequence as an infinite matrix, M; and P = Pascal's triangle as an infinite lower triangular matrix. The triangle A124802 = P*M, with the zeros deleted.
%e A039834, (1, 0, 1, -1, 2, -3, 5, -8, 13...) = the diagonal of M, then the first few rows of P*M =
