I don't need these specific numbers. The example was just a concise way to show that there is a problem. The randomness is only used internally. Namely, in my cohomology programs happens the following: (1) Input is some group. (2) Internally, some additional data are computed, using GAP functions such as IsomorphismGroups, SylowSubgroup etc. Some of these functions use a randomized algorithm, and according to gap-support, GAP does not provide a deterministic version of these algorithms. (3) The ring presentation will depend on the internal data computed in (2). (4) In order to write tests (not only to evaluate test results), I need a computationally unique machine independent ring presentation. As the example shows, in order to achieve (4) it does not suffice to reset GAP's random generator, since it is machine dependent.
