New description:
This patch introduces the following functions-
{{{
CanonicalFano SmoothFano
ReflexiveFano TerminalFano
PolytopeSmallPolygon lReflexive
LDP
}}}
These read from the data stored in this
spkg:[http://coates.ma.ic.ac.uk/grdb_polytopes-0.1.spkg]
by using the new private function `_GRDBBlockReader` to access
classifications of the above Fano polytopes originally stored on the
[http://grdb.lboro.ac.uk Graded Ring Database] and return
`LatticePolytope` instances.
The implementation is similar that of #13115 where we provide a module
`lattice_polytopes` to act as a namespace for these functions which are
situated elsewhere, giving the option to concentrate all future examples
of lattice polytopes here.
Install the latest SPKG above and the latest patch below.
