A cuboctahedron, also called the dymaxion or heptaparallelohedron, is Archimedean  solid .It is one of the two  convex quasiregular polyhedra. It  is  uniform polyhedron      and Wenninger model .A cuboctahedron appears in the lower left as one of the polyhedral "stars" in M. C. Escher's 1948 wood engraving "Stars" (Forty 2003, Plate 43), as well is in the mezzotint "Crystal" (Bool et al. 1982, p. 293).If a cuboctahedron is oriented with triangles on top and bottom, the two halves may be rotated one sixth of a turn with respect to each other to obtain Johnson solid , the triangular orthobicupola.the cuboctahedroncan be obtained by truncation of a Platonic solid
