The question is asked, “Is this a new construction of a basic geometry?”

Five-tetrahedrons, five-octahedrons, five tetrahedrons and their gap
In July 2022, we asked the question, “Does it have a name?” Nobody seemed to know. So, on November 22, stopping for lunch in the little town of Unadilla, Georgia in a little Subway sandwich shoppe, I was telling Hattie how no scholars had a name of the object. She asked, “How many sides does it have?” As you can see, it is not a straight-forward answer. Within our squishy geometry where the gap would be eliminated, I said, “20.” Hattie looked up the Greek work, eikosi, for 20. A little like its English, icosa, this peculiar object was first called an eikosihedron. Using the Greek word would distinguish it from the icosahedron with twenty tetrahedrons. The eikosihedron is defined by fifteen objects (five octahedrons and ten tetrahedrons, and by the 7.35610+ degree gap.
