A multi-dimensional equation of the dispersionless Hirota type is said to be
integrable if it possesses infinitely many reductions to a family of
commuting (1+1)-dimensional systems.
The integrability conditions constitute a complicated overdetermined system
of PDEs, which is in involution. This system possesses a remarkable
Sp(6)-invariance, suggesting a connection with the theory of hypersurfaces
of the Lagrangian Grassmanian.
