We characterize which pseudocomplemented De Morgan algebras are congruencepermutable, congruenceuniform, have the principal join property, and have the principal congruence property. We use Priestley Duality for pseudocomplemented De Morgan algebras obtained by combining the known dualities of distributive palgebras due to Priestley and for De Morgan algebras due to Cornish and Fowler. This is a joint work with H. P. Sankappanavar.
