Hi there,
I am trying to get my code moved to the source files, but am finding
some problems (it is my first time!). What I did was:
- cloning sage to my own branch (called sage-groups),
- Added a new file $SAGE_ROOT/devel/sage-groups/sage/groups/
group_conjugacy_class.py with my class code
-
[...]
And finally for those groups who are not known to gap, the fallback
(sage-only) method should be in the category FiniteGroups to be inherited by
any group.
I hadn't thought of that. Since all the groups I used are defined as
permutation groups I never ran into trouble, but now that
You are absolutely right, GAP deals perfectly with the conjugacy
classes of groups of matrices.
Apparently what is not implemented is the conversion of GAP matrices
back into sage matrices:
sage: F = GF(5)
sage: gens = [matrix(F,2,[1,2, -1, 1]), matrix(F,2, [1,1, 0,1])]
sage: G =
Hi all,
I have been working on this and after a while decided that my original
approach wasn't the most appropriate and started rewriting everything
for scratch.
After thinking about this problem making conjugacy_class a method
that returns a list (or set) didn't feel right. GAP has many methods

Speaking of such groups, this is a bit mysterious (sometimes a
calculation will say to download the optional database, sometimes no

However, I thing it should be a method of the group:
G.conjugacy_class(g).
that was my original idea, to keep it close to GAP original
definition.
Or even of the element itself since it knows G as it's parent:

My question: would it be interesting to include the wrapper for the
GAP function in sage?

There are places where Sage/GAP just give you one of something, when
you might want all of them, and it is simply conjugacy that will
produce them

This also makes sense. I don't really know which choice would be
better. Maybe having both, doing something like
def conjugacy_class(self):
G = self.parent()
Yes, have a look at sage/groups/group.pyx. It has a FiniteGroup
class, where I think you should put your main method (that's what
Florent said as well, I think).
Yep ! This will probably needs some cleanup when we will merge categories with
the other generic stuff but I think this is the
