a permutation group
alpha
posint; the point whose stabilizer is to be computed
The stabilizer of a point α under a permutation group G is the set of elements of G that fix α. It is a subgroup of G. That is, an element g in G belongs to the stabilizer of α if αg=α.
The Stabilizer( alpha, G ) command computes the stabilizer of the point alpha under the action of the permutation group G.
The Stabiliser command is provided as an alias.
