Noun

pentagonal icositetrahedron (plural pentagonal icositetrahedra)

  1. (geometry) A Catalan solid with 24 irregular pentagonal faces, 60 edges and 38 vertices, being the dual of the snub cube.
    • 1922, Alfred Edwin Howard Tutton, Crystallography and Practical Crystal Measurement‎[1], page 167:
      The pentagonal icositetrahedron is enantiomorphous, and as such the two possible varieties are distinct forms of the solid, which cannot be brought into identity by rotation.
