Comment (by stumpc5):
Here is another problem to fix, but I rather think this is a problem in
!FindStat since there is neither a {{{JSON}}} json file for {{{St000288}}}
nor a {{{pdf}}}:
{{{
sage: findstat({l:l.length() for l in Partitions(4)})
---------------------------------------------------------------------------
IOError Traceback (most recent call
last)
...
IOError: FindStat did not answer with a json response: St000288 is not a
FindStat statistic identifier.
}}}
One quick idea: what about having a method {{{findstat.collections}}} such
that
{{{
sage: findstat.collections()
{'Binary words': 'not supported',
'Dyck paths': 'supported',
'Permutations': 'supported'}
}}}
and if an unsupported collection is used, we throw an error like the one
you have.
Good:
{{{
sage: findstat(289)
ValueError: Could not find FindStat collection for Binary words.
}}}
but unclear what to do in the above situation where a binary word
statistic is found and we cannot throw an error...
