Dear Mr. and Ms. forum,
Uptill now things go well. But we don't understand the following

The problem is in the computing of images.
GAP computes Image (c, A), but not e.g Image(c, A*B) (the function
Image in this example seems to work only with generators A, B).
This bug was fixed in GAP 3.1 Patchlevel 1:
This is the first upgrade for GAP 3.1. It brings version 3 release 1 (V3R1) to version 3 release 1 patchlevel 1 (V3R1P1).
The priority of this upgrade is low.[...]
The function 'Image' was fixed to test the cases correctly. 'Image'
signalled an error when called to compute the image of a matrix under a
Please update to GAP 3.2, or if you do not have ftp access, try at
least to upgrade to GAP 3.1 patchlevel 3.
