Some combinatorial aspects of congruence lattice representations
A finite distributive lattice D can be represented as the congruence lattice, Con L, of a finite lattice L. We shall discuss the combinatorial aspects of such - and related - representations, specifically, optimal size, breadth, and degree of symmetry. (C) 1999-Elsevier Science B.V. All rights reserved.
