Comment (by hthomas):
Hi Frédéric and Christian--
Sorry not to have got around to finishing refereeing this, and I'm glad
Christian has instead.
Christian, these (a,b,m) lattices are clearly intervals inside the
m-Tamari. So they are lattices. For that reason I wouldn't say that the
lattice property is conjectural, and I'm happy with what Frédéric wrote
originally. (But I don't mean to delay a positive review over this.)
cheers,
Hugh
