Faster function for working with cosets
I would like to get the cosets of a non-normal subgroup and in the documentation for the
.cosets() method here:
there is a Note: that says
Sage and GAP provide more sophisticated functions for working quickly with cosets of larger groups.
but doesn't mention what these functions are. I was hoping that someone could point me to these functions.
If it makes a difference, I want to iterate over a set of coset representatives and it will all be done in a permutation group.
