Oho. So why don't you at least put a pointer to this paper into the
documentation?
However,
Page 5:
guessADE [1,1,2,9/2,32/3,625/24,324/5,117649/720,131072/315,
4782969/4480]
returns
[[x^n]f(x) : -xf'(x) + f(x)^3 - f(x)^2 = 0, f(0) = 1, f'(0) = 1].
???
Nowhere is actually explained what that notation means. :-(
Is this a common notation? Can you please give a definition for that
notation?
Let me guess... The sequence that is written after guessADE is obtained by
[coefficient(f(x), n) for f in F |
-xf'(x) + f(x)^3 - f(x)^2 = 0 and f(0) = 1 and f'(0) = 1]
where F is the space of all (differentiable) functions? Oh, no, F is
K[[x]], right?

PS: You probably don't want me as a reviewer of that paper. ;-)
