Bérczi, Tamás Equilateral triangle polyhedra. (English) Zbl 1092.51507 Symmetry Cult. Sci. 13, No. 1-2, 191-198 (2002). Summary: We show that it is easy to build polyhedra covered with congruent equilateral triangles, having the symmetries of the Platonic or Archimedean solids. The method is that we replace the faces of the base-polyhedron with modules which are built from congruent equilateral triangles. The modules can be completed from simple Platonic solids, namely such as tetrahedra, octahedra, and icosahedra. Omitting some of the faces of the base-polyhedron we get hole solids. We try to give notation to the modules and to the solids. MSC: 51M20 Polyhedra and polytopes; regular figures, division of spaces PDFBibTeX XMLCite \textit{T. Bérczi}, Symmetry Cult.
