Nothing, in particular.
According to the Euler characteristic, regular polyhedra satisfy the following:
Face + Vertices = Edges + 2
This gives
Face + Vertices + Edges = 2 + 2*Edges = 2*(1+Edges) which, since it has the variable "edges" on the RHS as well, is not particularly helpful nor informative.
