● A program to solve the word problem of lattices
● A program to test associativity conditions
● A program
to test if a lattice identity holds in the congruence variety of the variety
generated
by the quaternion group
Lattice drowing demo ( by Ralph Freese)
Universal Algebra Calculator (Emil Kiss's algebra calculator),
● The calculator now uses the lattice drawing program to display congruence lattices.
Concept analysis (Darmstadt, Peter Burmeister)
The Dresden Formal Concept Analysis Program (Dresden, Bernhard Ganter)
Finite projective planes (hungarian)
Results: (with George Grätzer)
