The paper contains generalisations of tools and previously known results for nonsingular toric Fano varieties. As applications we obtain new classification results, bounds of invariants and formulate conjectures concerning combinatorial and geometrical properties of reflexive polytopes.AMS-LaTeX, 29 pages with 5 figuresAlgebraic GeometryCombinatorics14J45; 14M25; 52B20text
