  • But math-crazy Lovecraft would have known that a trapezohedron is an "antiprism."

    Kenneth Hite's Journal

  • What I and apparently LaVey thought was a trapezohedron -- a polyhedron with trapezoids for sides -- is actually a frustum.

  • So the Hancock Building, which so delightfully crouches on LaVey's birthplace, is not, despite what I've said in person and print for the better part of 20 years now, the world's largest trapezohedron.

    Kenneth Hite's Journal

  • It is found massive and in trapezohedron crystals weighing from six to eighteen pounds each, and through many intervening forms down to the small fractured masses in Kinzigite and in sands.
