Seqfans,
Where is the rectangular table referred to by these sequences?
A040027 Main diagonal of an array of binomial recurrence coefficients.
0, 1, 1, 3, 9, 31, 121, 523, 2469, 12611, 69161, 404663,
A045501 Second diagonal in table of binomial recurrence coefficients.
1, 1, 4, 14, 54, 233, 1101, 5625, 30846,
A045499 Third diagonal in table of binomial recurrence coefficients.
1, 1, 5, 20, 85, 400, 2046, 11226, 65676, 407787, 2675410,
A045500 Fourth diagonal in table of binomial recurrence coefficients.
1, 1, 6, 27, 125, 635, 3488, 20425, 126817, 831915, 5744784, 41618459
(AUTHOR of these sequences: H. W. Gould)
The closest thing I can find is Emeric Deutsch's recent triangle A124496,
in which these sequences appear as columns.
The lower half of the table (I guess) must look like this:
1, ...
1, 1, ...
1, 1, 3, ...
1, 1, 4, 9, ...
1, 1, 5, 14, 31, ...
1, 1, 6, 20, 54, 121, ...
1, 1, 7, 27, 85, 233, 523, ...
1, 1, 8, 35, 125, 400, 1101, 2469, ...
1, 1, 9, 44, 175, 635, 2046, 5625, 12611, ...
Is the complete table in the OEIS?
If not, it certainly should be.
Paul
