Incidence Geometries (New)

Magma 2.7 contains facilities for creating and computing with incidence geometries and coset geometries. These have been developed by Dimitri Leemans (Brussels).

Features:

• Creation of incidence geometries
• Set of types, rank
• Diagram, incidence graph, elements
• Residue, truncation
• Properties: flag-transitive geometry, residually connected, firm, thin, thick
• Automorphism group
• Correlation group
