sentences:  A lattice section of a skew lattice formula_17 is a sublattice formula_108 of formula_17 meeting each formula_29-class of formula_17 at a single element.formula_108 is thus an internal copy of the lattice formula_62 with the composition formula_114 being an isomorphism.All symmetric skew lattices for which |S/D| \leq \aleph_0, admit a lattice section.
