     * //[[https://github.com/apaffenholz/polymake_polyhedral_adjunction|polyhedral_adjunction]]//: This extension provides properties and constructions used in [[http://arxiv.org/abs/1105.2415|DiRocco, Haase, Nill, Paffenholz: Polyhedral Adjunction Theory, arxiv:1105:2415]]. In particular, it computes the nef value and the Q-codegree of a polytope.     * //[[https://github.com/apaffenholz/polymake_polyhedral_adjunction|polyhedral_adjunction]]//: This extension provides properties and constructions used in [[http://arxiv.org/abs/1105.2415|DiRocco, Haase, Nill, Paffenholz: Polyhedral Adjunction Theory, arxiv:1105:2415]]. In particular, it computes the nef value and the Q-codegree of a polytope.
-    * //Toric Varieties//: Defines a new property for toric varieties associated to a fan and divisors on that variety. Computes properties of the variety and the divisors, and the cone of nef and effective divisors. To use this extension you need the short lattice basis extension above.
