poly-<num>d.x(1) computes data of a polytope

Other Alias

poly.x

## SYNOPSIS

poly.x [-<Option-string>] [in-file [out-file]]

## DESCRIPTION

Computes data of a polytope P

The poly-<num>d.x variant programs, where <num> is one of 4, 5, 6 and 11 work in different dimensions ; poly.x defaults to dimension 6.

## Options (concatenate any number of them into <Option-string>):

h print this information
f use as filter
g general output ; for P reflexive: numbers of (dual) points/vertices, Hodge numbers and if P is not reflexive: numbers of points, vertices, equations

p points of P

v vertices of P
e equations of P/vertices of P-dual
m pairing matrix between vertices and equations
d points of P-dual (only if P reflexive)
a all of the above except h,f
l LG-`Hodge numbers' from single weight input
r ignore non-reflexive input
D dual polytope as input (ref only)
n do not complete polytope or calculate Hodge numbers
i incidence information
s check for span property (only if P from CWS)
I check for IP property
S number of symmetries
T upper triangular form
N normal form
t traced normal form computation
V IP simplices among vertices of P*
P IP simplices among points of P* (with 1<=codim<=# when # is set)
Z lattice quotients for IP simplices
# #=1,2,3 fibers spanned by IP simplices with codim<=#
## ##=11,22,33,(12,23): all (fibered) fibers with specified codim(s)
when combined: ### = (##)#
A affine normal form
B Barycenter and lattice volume [# ... points at deg #]
F print all facets
G Gorenstein: divisible by I>1
L like 'l' with Hodge data for twisted sectors
U simplicial facets in N-lattice
U1 Fano (simplicial and unimodular facets in N-lattice)
U5 5d fano from reflexive 4d projections (M lattice)
C1 conifold CY (unimodular or square 2-faces)
C2 conifold FANO (divisible by 2 & basic 2 faces)
E symmetries related to Einstein-Kaehler Metrics

## Input

degrees and weights `d1 w11 w12 ... d2 w21 w22 ...' or `d np' or `np d' (d=Dimension, np=#[points]) and (after newline) np*d coordinates

## Output

as specified by options
