No real need for a defence in my view, terse at times, while often enough verbose, superseek never omits a chance to grab me by the nose and *point*! Either right or wrong, its systematic doggedness is highly appreciated by the critical user. .. who, of course, needs to remain critical after getting a possible hit.

I fed A180238 to gfun via Maple9 --- and strange to say, gfun replied straight away "FAIL". So as I suspected, it is nonsense; and there appear to be bugs both in the way superseeker is to utilising the gfun package, and its output of the results; while the documentation leaves something to be desired (like, some documentation)!
Superseeker would say that WFL was not familiar with gfun, which has a lot of commands.
Look:
s1:=[1,3,9,27,75,189,447,951,1911,3621];
(that is A180238)
listtoalgeq(s1,y(x),[lgdegf]); 2 3 [-27 + 27 y(x) - 9 y(x) + y(x) , lgdegf]
The result may be nonsense, but Superseeker feels an obligation to report it, since once in a while it finds useful things.
As for documentation, the help file (send an empty email to superseeker@research.att.com) describes what it does. It states that it uses gfun, but of course does not show the large set of descriptions of all the gfun commands.
And as I said earlier the full Superseeker code can be seen on the OEIS web site.
Best regards Neil
PS The web page cite.html (on the OEIS site) mentions quite a few results that were found with the aid of Superseeker.
