I have the following question concerning GAP:

If I want to stop a calculation, how can I do this?

I know the command Ctrl+Z, but then GAP is closed.

I am using Linux Ubuntu 14.

Thanks for the help!

CTRL-C will interrupt a calculation (and enter the break loop -- type quit; or press CTRL-D to exit it). Note that some calculations purely within the kernel (e.g. matrix inversion) cannot be interrupted.
