| Ockham algebras with pseudocomplementation |
The variety 
consists of those algebras
of type
, where
is an Ockham algebra,
is a p-algebra, and the unary operations f and 
commute. We describe the structure of the subdirectly irreducible
algebras that belong to the subclass
characterised by
the property f3=f, and give a description of the lattice of
subvarieties of
.
