Currently in Sage, SetPartitions
are not proper Parent
and uses the old deprecated CombinatorialClass
framework. This framework was writen before UniqueRepresentation
. As a consequence
sage: isinstance(SetPartitions(5), UniqueRepresentation)
False
We are currently in the process of removing CombinatorialClass
and cleaning the code depending of it. See for example trac ticket #13552, #12913, #9265. Nothing is currently done on set partitions.
