Congruence Lattices of Finite Lattices as Concept Lattices

  • Sigrid Knecht

In formal concept analysis it is of increasing interest to compute and to represent congruence lattices of finite lattices (for instance, to assist adequate drawings of concept lattices). In this note we give a representation of such congruence lattices as concept lattices which allows the use of developed computer programs to determine and to draw those congruence lattices. For basic notions and results of formal concept analysis we refer to [3] and [5].
