Dear GAP-Forum,

Shahriar Mokhtari asked:

Following is a piece of gap code which runs perfectly in the version 3
release 4 but gives error in release 4.4. Could any body give the reason?

Just to avoid misunderstandings and confusion with GAP4: I suppose you are
talking about version 3.4.4.

The code for handling matrix groups via a faithful permutation
representation has been improved in the step of 3.4.3 to 3.4.4.
Unfortunately this introduced an error in the conjugacy test for elements.

This error was corrected in fix2 (announced in the Forum on 10-Jun-97).
You can get this fix from the GAP bugfixes web page:


or via ftp in the directory:


(While you are at it, you should also install the other bugfixes on this
page *in their natural order*)

I hope this is of help.

Best regards,

Alexander Hulpke
