Abstract

We consider the classical 42 algebra from the integrable system viewpoint. The integrable evolution equations associated with the 42 algebra are constructed and the Miura maps , consequently modifications, are presented. Modifying the Miura maps, we give a free field realization the classical 42 algebra. We also construct the Toda type integrable systems for it.
