New description:
It is not possible to use (in a straightforward way) univariate polynomial
in libgap
{{{
sage: R.<x> = ZZ[]
sage: libgap(x^5+2*x+1)
Traceback (most recent call last):
...
ValueError: libGAP: Error, Variable: 'x' must have a value
}}}
And multivariate polynomials with either gap or libgap
{{{
sage: R.<x,y> = ZZ[]
sage: gap(x+y)
Traceback (most recent call last):
...
TypeError: Gap produced error output
sage: libgap(x+y)
Traceback (most recent call last):
...
ValueError: libGAP: Error, Variable: 'x' must have a value
}}}
The above ticket (partially based on #2420) implement the above
conversions.
Note: The conversion from gap/libgap to Sage does not work as well and
will be dealt with in #21020.
