#4419: [with patch, needs review] conversion of Permutations to GAP not
implemented

Comment (by wdj):
I don't see how this fixes the original problem. I get this:
{{{
sage: p = gap(Permutation('(1,2,3)'))
sage: q = gap(Permutation('()'))
---------------------------------------------------------------------------
ValueError Traceback (most recent call
last)
<snip>
ValueError: invalid literal for int() with base 10: ''
}}}
and this:
{{{
sage: q = gap(Permutation(()))
---------------------------------------------------------------------------
TypeError Traceback (most recent call
last)
<snip>
TypeError: not enough arguments for format string
}}}
It seems to me you want Permutation to work like
PermutationGroupElement does here:
{{{
sage: p = gap(PermutationGroupElement('(1,2,3)'))
sage: q = gap(PermutationGroupElement('()'))
sage: gap.Group([p, q])
Group( [ (1,2,3), () ] )
sage: gap.Group([p]) == gap.Group([p, q])
True
}}}
Is that correct?
