Dear Gap Forum,
As always, many many thanks to the creators and maintainers
of Gap. Accept my apologies if this question has been addressed
in this forum before.
Unless I know there will be a lengthy calculation involved,
I tend to use Gap interactively. It happens that I define a number of
groups, elements, maps, etc with my own names. My question is whether
there is a method of recalling the names I have used.
For example, suppose I issue the following command:
gap> grp := Group((1,2,3,4));; a := (1,3)(2,4); els := Elements(grp);
I may refer to the group, the element, and the list of elements
by the names grp, a and els. Can I get a list of those names as the
ones I have already used?
