We prove that the subgroups of the Thompson group V which are closed under a binary operation introduced by K.S. Brown are in bijective correspondence with a class of varieties of algebras with a single binary operation. In addition, we prove that there are exactly three such proper subgroups which contain the Thompson group F. © 2007 Springer.
