[GAP Forum] orbits of a set under induced group action

[reichard at maths.uwa.edu.au]

Hi Abhishek, hi Laurent,

the approach described by Laurent works fine if X is reasonably small, say
up to 20 elements. For larger X (and hopefully a larger group) you can
construct representatives of the orbits without storing all sets
simultaneously, e.g., by orderly generation[1]. If you are interested I
can make available some code which performs this task.

Regards,
Sven.
