Quantities associated to the subgroup lattice of a finite group.

We begin by discussing the Möbius function of a finite group G. This function is primarily used to determine enumerative functions associated to G, such as the number of ordered generating pairs of elements of G. We illustrate this method in the specific case of the small Ree groups by using their natural 2-transitive permutation representation. We also give some results on the generation and asymptotic generation of the small Ree groups. Finally, we will describe the connection between the Möbius function and the topology of the subgroup lattice regarded as a simplicial complex.
