Package palp

http://hep.itp.tuwien.ac.at/~kreuzer/CY/CYpalp.html

PALP contains routines for vertex and facet enumeration, computation of
incidences and symmetries, as well as completion of the set of lattice
points in the convex hull of a given set of points. In addition, there
are procedures specialized to reflexive polytopes such as the enumeration
of reflexive subpolytopes, and applications to toric geometry and string
theory, like the computation of Hodge data and fibration structures for
toric Calabi-Yau varieties.
