nef-<num>d.x## SYNOPSIS

**nef.x**

*<Options>*

## DESCRIPTION

The nef-<num>d.x variant programs, where <num> is one of 4, 5, 6 and 11 work in different dimensions ; nef.x defaults to dimension 6.## 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
**-G**- Gorenstein cone: input <-> support polytope
