In mathematics, a group action on a space is a group homomorphism of a given group into the group of transformations of the space. Similarly, a group action on a mathematical structure is a group homomorphism of a group into the automorphism group of the structure. It is said that the group acts on the space or structure.

WebThe cardinality of each orbit equals the index of the stabilizer of a point in that orbit, so as you say the possible indices for the stabilizer are 1, 11, and 13, and these are the possible cardinalities of each orbit (the other alternative 143 is ruled out for being larger than 108 ).

WebA group action is a representation of the elements of a group as symmetries of a set. Many groups have a natural group action coming from their construction; e.g. the dihedral group D_4 D4 acts on the vertices of a square because the group is given as a set of symmetries of the square.
