Help needed
Please help in understanding the series 1, 2, 6, 8, 22, 32, 84, 128,... that is Sloane A081672 and is titled "Expansion of exp(2x)exp(0)+BesselI_0(2x)."
I do not understand the term "expansion" in above context. Further do you recognize the following series in the same contents? 1,3,13, 27, 105, 243, 889, 3^7,.... 1,4, 22, 64, 310, 1024, 4636, ... 1,5, 33, 125, 721, 3125, 16905, ... These series I generate from any prime but in modula p. best regards Anton Last fiddled with by AntonVrba on 20070303 at 11:39

Glanced at the OEIS entry  it mentions an "Inverse binomial transform", so my guess is that that leads to an oo series, and these are the coefficients.
But don't take my (speculative) word for it  suggest you email the entry author, whose eaddress is attached to the entry.

I don't recognize your sequences either  modula p means "mod p" ? then for primes smaller than 100 I dont understand how to get values > 100, and 'mod p' should give different things once you have a number larger than p (and before there's no use in saying mod p)...
