Comment (by nthiery):
Replying to [comment:5 chapoton]:
> Thinking again about this, it now seems to me that q_jordan should be a
method of the class Partitions. This is really the job of a partition
constructor to check that something is a partition.
> Maybe this would also solve the hash problem ?
Sorry I did not comment earlier; the network at the airport was crappy. It
would certainly be natural for the input to q_jordan to be a partition,
and it should indeed fix the problem.
That being said, this does not necessarily imply that q_jordan should be a
method of partitions. It might be more natural to put instead q_jordan
with the other q-analogues, as a function taking a partition as input.
I let you judge which option is best.
Cheers,
Nicolas
