Programs

Lattice drawing  ( by Ralph Freese)

Universal Algebra Calculator (Emil Kiss's algebra calculator),

       ● The calculator now uses the lattice drawing program to display congruence lattices.

The Dresden Formal Concept Analysis Program (Dresden, Bernhard Ganter)

Finite projective planes  (in Hungarian)

Desargues Theorem (Java applet)

Two constructions:

        ● Isoform lattices, pruning of intervals

          ● The M₃[D] construction

                           You can see M₃[C₃]  with the lattice drawing program   (Freese) if you fill in the text field on the applet with

www.math.bme.hu/~schmidt/tomi.lat

 To see   M₃[C₄]  use 

www.math.bme.hu/~schmidt/tomiy.lat

Java applet
