GroupCentralizer[group,g]

returns the centralizer of the element g in group.

Details

  • The centralizer of an element g in group is the subgroup of elements of group that commute with g.

Examples

Basic Examples  (1)

Take a permutation group:

And a permutation:

This is the subgroup of permutations in the group that commutes with the permutation g:

Scope  (1)

Take a permutation group:

And a permutation:

This is the subgroup of permutations in the group that commutes with the permutation g:

Check the result by direct computation of products with all elements:

This function checks that a permutation h commutes with g:

All 16 permutations in the centralizer commute with g:
