"Facts about finite algebras"

If an algebra A is finite, what can we say about the variety HSP(A)? We'll show that such varieties are locally finite, i.e. its members which are finitely generated are in fact finite. Further, if such a variety has any infinite subdirectly irreducible algebras, then in fact it has arbitrarily large finite ones as well.
