-----------------------------+---------------------------------------
The permutation group method to_presentation wraps the GAP function
``IsomorphismFpGroupByGenerators`` which yields an isomorphism from a
given group to an isomorphic finite presentation. ``to_presentation``
takes the image of the isomorphism returned by this function and wraps it
as a Sage finitely presented group.
{{{
sage: G = DihedralGroup(8); G
Dihedral group of order 16 as a permutation group
sage: G.to_presentation()
Finitely presented group < a, b | b^2, b*a^-1*b*a^-1, a^8 >
}}}
Depends on #14790 which gives the python generator object needed for
variable names.
