Comment(by vbraun):
Newest version can convert various GAP datatypes back to Sage, for example
cyclotomic numbers
{{{
sage: libgap('5/3 + 7*E(3)').sage()
7*zeta3 + 5/3
}}}
and permutations:
{{{
sage: generators = libgap.AlternatingGroup(4).GeneratorsOfGroup().sage()
sage: generators # a Sage list of Sage permutations!
[(1,2,3), (2,3,4)]
sage: PermutationGroup(generators).cardinality() # computed in Sage
12
sage: libgap.AlternatingGroup(4).Size() # computed in GAP
12
}}}
