Data Libraries

GAP contains several data libraries. Some of these are parts of the core GAP system, while some others are technically GAP packages and must be loaded using the LoadPackage mechanism.

Data libraries which are parts of the core GAP system:

• Basic Groups
  Cyclic, abelian, dihedral, extraspecial, alternating, symmetric, Mathieu, Suzuki, and Ree groups.
   
• Classical Groups
  Linear, unitary, symplectic, and orthogonal groups.
   
• Perfect Groups   by D. Holt, W. Plesken, and V. Felsch
  Almost all perfect groups of order up to 10 ⁶.
   
• Integral Matrix Groups   by W. Plesken, B. Souvignier, G. Nebe, and V. Felsch.
  Irreducible maximal finite integral matrix groups of dimension up to 31.
   
• Lie Algebras
  Free, Full Linear, and Simple Lie Algebras.
