Doctest failure with gap3 in reflection group element hashing
**********************************************************************
File "src/sage/combinat/root_system/reflection_group_element.pyx", line 71, in sage.combinat.root_system.reflection_group_element.ComplexReflectionGroupElement.__hash__
Failed example:
WB_hash.intersection(WC_hash) # optional  gap3
Expected:
set()
Got:
{9223363265629785093,
...
Perhaps we should change the test to
sage: len(WB_hash.intersection(WC_hash)) < WB.cardinality()
True
as there is no guarantee that the parents have sufficiently different hashes to lead to them being disjoint:
sage: WB = ReflectionGroup(['B',5])
sage: WC = ReflectionGroup(['C',5])
sage: hash(WC)
9223363307533887018
sage: hash(WB)
9223363307530756153
