## Synopsis

**nef-6d.x** *<Options>*

## Description

This is 'bin/nef-6d.x': calculate Hodge numbers of nef-partitions

Options: **-h** prints this information

- -f or -
use as filter; otherwise parameters denote I/O files

- -N
input is in N-lattice (default is M)

- -H
gives full list of Hodge numbers

- -Lv
prints L vector of Vertices (in N-lattice)

- -Lp
prints L vector of Points (in N-lattice)

- -p
prints only partitions, no Hodge numbers

- -D
calculates also direct products

- -P
calculates also projections

- -t
full time info

- -cCODIM
codimension (default = 2)

- -Fcodim
fibrations up to codim (default = 2)

- -y
prints poly/CWS in M lattice if it has nef-partitions

- -S
information about #points calculated in S-Poly

- -T
checks Serre-duality

- -s
don't remove symmetric nef-partitions

- -n
prints polytope only if it has nef-partitions

- -v
prints vertices and #points of input polytope in one line; with

**-u**,**-l**the output is limited by #points:- -uPOINTS
... upper limit of #points (default = POINT_Nmax)

- -lPOINTS
... lower limit of #points (default = 0)

- -m
starts with [d w1 w2 ... wk d=d_1 d_2 (Minkowski sum)

- -R
prints vertices of input if not reflexive

- -V
prints vertices of N-lattice polytope

- -Q
only direct products (up to lattice Quotient)

- -gNUMBER
prints points of Gorenstein polytope in N-lattice

- -dNUMBER
prints points of Gorenstein polytope in M-lattice

- if NUMBER = 0 ... no
0/1 info

- if NUMBER = 1 ... no redundant
0/1 info (=default)

- if NUMBER = 2 ... full
0/1 info
