schreier_sims.intersection(result: SchreierSims, x: SchreierSims, y: SchreierSims) → None

Find the intersection of two permutation groups.

This function finds the intersection of two permutation groups. It modifies the first parameter result to be the SchreierSims object corresponding to the intersection of x and y.

Parameters:

• result (SchreierSims) – an empty SchreierSims object that will hold the result.

• x (SchreierSims) – the first group of the intersection.

• y (SchreierSims) – the second group of the intersection.

Raises:

LibsemigroupsError – if result is not empty.
