Weight systems for 5 and more dimensions
- The database of all weight systems for 5d polyhedra with the IP property has a
searchable web front-end.
It is now also
available in Parquet format at the Hugging Face Hub.

- All files
- The format of the files is
w1 ... w6 deg=d M:#p #v N:#p #v H:h11,h12,h13 [chi] . . . (reflexive)
w1 ... w6 deg=d M:#p #v N:#p #v V:h11,h12,h13 [chi] . . . (reflexive, transverse)
w1 ... w6 deg=d M:#p #v F:#f V:h11,h12,h13 [chi] . . . (transverse)
(or with the standard PALP format "d w1 ..." instead of "w1 ... deg=d"), where
- #p (#v) = number of points (vertices) in the M or N lattice;
#f = number of facets (for non-reflexive polyhedra);
- H = toric Hodge data (non-transverse case, Batyrev's formula),
V = chiral ring data (Vafa's formula;
for all weights that define both reflexive polytopes and transverse
polynomials, i.e. ... N ... V ..., we checked that both formulas give the
same result).
- History and references:
- In hep-th/9701023
Klemm, Lian, Roan and Yau computed all Fermat weights
and the transverse weights up to degree 400.
- In hep-th/9701175
Kreuzer and Skarke computed all reflexive weights up to degree 150 and all transverse
weights up to degree 4000.
- In hep-th/9812195
Lynker, Schimmrigk and Wisskirchen constructed all 1,100,055
transverse configurations. We took their weights and added the
M- and N-lattice data in our file format.
- Later Max Kreuzer also computed all
reflexive 4-fold weight systems up to degree 300 and all
reflexive 5-fold weight systems up to degree 150. These can
be used as starting points for complete intersections
of codimension 2 and 3, respectively (cf.
math.AG/0103214).
- In arXiv:1808.02422
Schöller and Skarke found all weight systems that determine 5d IP
polytopes.
- The 6d and 7d weighted projective spaces up to degree 200 were first constructed by Hirst and Gherardini in the context of a machine learning project (see arXiv:2311.17146). The present lists, produced by a recently optimized version of PALP, are consistent with their results.
