sentences:  In particular, given two incomparable D-classes A and B with join D-class J and meet D-class formula_334 in formula_36, interesting connections arise between the two coset decompositions of J (or M) with respect to A and B.Thus a skew lattice may be viewed as a coset atlas of rectangular skew lattices placed on the vertices of a lattice and coset bijections between them, the latter seen as partial isomorphisms
  between the rectangular algebras with each coset bijection determining a corresponding pair of cosets.This perspective gives, in essence, the Hasse diagram of the skew lattice, which is easily
  drawn in cases of relatively small order.
