Description (last modified by vbraun)

This ticket implements an interface to read databases of reflexive polytopes:

  • Add databases in PALP format to the polytopes_db.spkg.
  • A class PALPreader that can read the palp output and yield it in various Sage representations.
  • Finally, this ticket contains a specialized PPL lattice polytope that is fast enough to construct to go through the 500 million 4-d reflexive polytopes and compute integral points.

The updated polytopes spkg is here: http://www.stp.dias.ie/~vbraun/Sage/spkg/polytopes_db-20120220.spkg
