Combining [14, Lemma 3] with [8] it can be proved that the following conditions for a variety V are equivalent: (1) No nontrivial algebra of V has a trivial subalgebra. (2) There exist unary terms 0 1 (w), ..., 0 N (w), 1 1 (w), ..., 1 N (w) such that V< 09 (w)=19 (w) Γ„ x= y, where 09 =(0 1 , ...,
