Dear seqfans,
There are only seven terms listed:
1, 3, 16, 139, 1750, 29388, 623909,
taken - I assume - from p. 147 of the cited Comtet paper.
Same paper gives
G:=exp(-1+(exp(z)-1)/2)*sum(exp(s*(s-1)*z/2)/s!,s=0..infinity);
as the exponential g.f.
Our computations (Maple and I) have given
1, 3, 16, 139, 1750, 29388, 624889, 16255738, 504717929,
i.e. a discrepancy in the 7th term.
Anybody interested in doublechecking?
Thanks.
