the sequence A006743

[Simon Plouffe]

This method uses maple and an old program I made
a couple of years ago, it is used (but somewhat modified)
in the current version of gfun.

But there are some differences I can't explain, it took me
2 months to tune up that program, it does work well, a bit
clumsy to use BUT it finds recurrences that gfun fails to
find.
in plain english, it is my own recurrence solver program.
it simply uses the msolve of maple and some simple tricks.
