Description (last modified by chapoton)

The Tamari lattice is a partial order on planar binary trees or Dyck paths.

(see Tamari Lattice in Wikipedia)

It has been generalized recently by F. Bergeron and his collaborators.

The patch below implements these lattices, and even more general versions.
