  • On regular and equivelar Leonardo polyhedra
    Gévay, Gábor ; Wills, Jörg M., 1937-
    A Leonardo polyhedron is a 2-manifold without boundary, embedded in Euclidean 3-space ▫${\mathbb E}^3$▫, built up of convex polygons and with the geometric symmetry (or rotation) group of a Platonic ... solid and of genus ▫$g \ge 2$▫. The polyhedra are named in honour of Leonardo's famous illustrations. Only six combinatorially regular Leonardo polyhedra are known: Coxeter's four regular skew polyhedra, and the polyhedral realizations of the regular maps by Klein of genus 3 and by Fricke and Klein of genus 5. In this paper we construct infinite series of equivelar (i.e. locally regular) Leonardo polyhedra, which share some properties with the regular ones, namely the same Schläfli symbols and related topological structure. So the weaker condition of local regularity allows a much greater variety of symmetric polyhedra.
