Great! Thanks. It becomes reasonable to start using the generic backend.
Next step: avoid the recomputation of vertices! The algorithm is currently
{{{
INPUT: vertices
OUTPUT: (vertices, hyperplanes)
ALGO:
1. compute hyperplanes from vertices (with no redundancy)
2. recompute vertices from hyperplanes (with no redundancy)
3. return (vertices, hyperplanes)
}}}
And it is precisely step 2. which fails for the 600-cell!
