I agree with Brendan that we should not play with the
standard definition of the binomial coefficients.
I.e., binomial(z,k) is 0 if k < 0
and the degree k polynomial z(z-1)...(z-k+1)/k! otherwise.
The non-standard definition of Maple -- with non-zero
values for some negative k -- has caused me many headaches
and is one of my biggest gripes with Maple. Any Maple
experts care to comment?
Also, are there instances in OEIS where non-standard
definitions of binomial(n,k) are used? Such usage should
definitely be noted.
