COMMENTS

Inverse binomial transform of the triangle shifts to left

(= adding I as right border, I = Identity matrix); resulting in reversed rows of A121207.

Left border = Bell numbers, A000110 = eigensequence of Pascal's triangle.

Successive columns from left to right = eigensequences of Pascal's triangle

deleting columns one at a time.

FORMULA

Triangle read by rows, 1 / ((-1)*A129184 * A051731 + I), I = Identity matrix. Equals reversal by rows of triangle A121207, then delete right border. A121207 begins: 1; 1, 1; 1, 1, 2 1, 1, 3, 5; ...
