--------------------------+-------------------------------------------------
As of now, certain kinds of sage objects can be converted into GAP
objects, but the resulting GAP objects cannot be converted back to sage
objects.
Examples of this are matrices over finite fields:
{{{
sage: g = matrix(GF(5),2,[1,2, -1, 1])
sage: gg = g._gap_()
sage: gg.sage()
---------------------------------------------------------------------------
NotImplementedError
}}}
{{{
sage: a = gap('E(9)')
sage: a
-E(9)^4-E(9)^7
sage: a.sage()
---------------------------------------------------------------------------
NotImplementedError
}}}
Being able to translate gap field elements into sage ones would help
accesing GAP character tables, and a good conversion of matrices would
allow many methods to be available for matrix groups.
