%N Triangle read by rows: matrix inverse of A110877.

%C A110877 can be generated from M^n * [1,0,0,0...] where M = an infinite tridiagonal matrix with 1's in the super and subdiagonals and (1,3,3,3...) in the main diagonal.

%C Up to signs the same as A124037. - _R. J. Mathar_, Sep 06 2013

%C Riordan array ((1+2*x)/(1+3*x+x^2), x/(1+3*x+x^2)). - _Philippe Deléham_, Mar 04 2014
