Abstract.
There are investigated classes of finite bands such that their subsemigroup
lattices
satisfy certain lattice-theoretical properties which are related with
the cardinalities
of the Green's classes of the considered bands, too. Mainly, there
are given
disjunctions of equations which define the classes of finite bands.
