dear seqfanners,

as happend a few times before, I'm flabbergasted by it:
[16 - 32 a(n) + 24 a(n)^2  - 8 a(n)^3  + a(n)^4 , lgdegf]
translated as:
sequence 1, 2, 4, 10, 24, 58, 126, 276, 561, ... offset 1 has an EGF  g[x] 
such that
g'(x)/g(x)  =   16 - 32 a(n) + 24 a(n)^2  - 8 a(n)^3  + a(n)^4

how am I supposed to proceed from here? Is this sufficient to generate the 
proposed sequence?

Wouter.
