Let G be a Lie group acting smoothly on a manifold M. A closed, nonsingular submanifold S ⊂ M is called maximally symmetric if its symmetry subgroup Gs ⊂ G has the maximal possible dimension, namely dim G s=dim S., and hence S=Gs · zo is an orbit of Gs · Maximally symmetric submanifolds are characterized by the property that all their differential invariants are constant. In this paper, we explain how to directly compute the numerical values of the differential invariants of a maximally symmetric submanifold from the infinitesimal generators of its symmetry group. The equivariant method of moving frames is applied to significantly simplify the resulting formulae. The method is illustrated by examples of curves and surfaces in various classical geometries.
