Looks like its time to be an advertiser again,
One of our students has recently completed his Magister Thesis
on the implementation of Nearring functions in GAP, and as
a byproduct has created GAP functions to do endomorphisms,
automorphisms etc of groups. Its probably time to upload it..
>From what i have heard from the people here who use it, the
package is beautiful :-)
I will try to have it uploaded within a few days
Cheers,
