characteristic is not 2). The action of the projective linear group on the projective line is sharply 3-transitive (faithful and 3-transitive), so the map is one-to-one...

and d2 = 24. The action of a group G on a set M is said to be transitive if, for every two elements s, t of M, there is some group element g such that...

1882, §39–40). A transitive subgroup of Sn is a subgroup whose action on {1, 2, ,..., n} is transitive. For example, the Galois group of a (finite) Galois...

In mathematics, a Frobenius group is a transitive permutation group on a finite set, such that no non-trivial element fixes more than one point and some...

chambers is this: Theorem: The Weyl group acts freely and transitively on the Weyl chambers. Thus, the order of the Weyl group is equal to the number of Weyl...

Equivalently, a principal homogeneous space for a group G is a non-empty set X on which G acts freely and transitively (meaning that, for any x, y in X, there exists...

known as group theory, the Higman–Sims group HS is a sporadic simple group of order    29⋅32⋅53⋅7⋅11 = 44352000 ≈ 4×107. The Schur multiplier has order...

22, 23 and 24 are multiply transitive permutation groups on n points. They are all subgroups of M24, which is a permutation group on 24 points. All the...

normal subgroup of a group need not be normal in the group. That is, normality is not a transitive relation. The smallest group exhibiting this phenomenon...

generates a one-parameter subgroup. If a group G acts on a space V, then a surface S ⊂ V is a surface of transitivity if S is invariant under G (i.e., ∀g ∈...
