F. Cornelius Jr. and Phill Schultz-based polynomials for the D_n Cartan Matrices in sequence A129862 that give a triangular sequence. %C A135185 These polynomials are suggested by Corollary 2.4 in the E. F. Cornelius Jr. and Phill Schultz paper. %C A135185 It appears that many other fundamental matrix sequences can be related to these Cornelius-Schultz polynomials by a similar treatment. %C A135185 Here a factor of 4 was necessary to convert them all to integer form. %H A135185 E.
