COMMENTS
| Triangle read by rows, A000012 * A115361; where A000012 = an infinite lower
triangular matrix with all 1's: [1; 1,1; 1,1,1;...] and A115361 = the ruler
function triangle. The operation A000012 * A115361 takes partial sums of
A115361 column terms starting fromt the top. [Gary W. Adamson (qntmpkt(AT)yahoo.com), Nov 27 2009]
Eigensequence of the triangle = A089067: (1, 3, 5, 13, 23, 51, 97, 207, ...). [Gary W. Adamson (qntmpkt(AT)yahoo.com), Nov 27 2009]
Row sums = A005187: (1, 3, 4, 7, 8, 10, 11, 15,...)
Left column = A070939 starting (1, 2, 2, 3, 3, 3, 3, 4, 4, 4,...).
