A034140 - A034150: formula

[zak seidov]

OK, 
Gordon, Neil, seqfans,

in that case,

i'd suggest to 

a) keep only 
1+n(n+1)/2 
nonzero (not non-zero!)
terms, 
with, e.g. n=10,11,...

b) add fini, full keys
and 

c) add Mmca:
CoefficientList[Product[(1 + x^i), {i, n}], x],
for relevant n's.

Right?
Zak
