Five tetrahedrons-five octahedrons-five tetrahedrons share a center point

Fifteen objects: five tetrahedrons, five octahedrons and five tetrahedrons also create a 7.35610+ degree gap.

Because there were no references on the web to the five-octahedral gap, on June 16, 2022, I sent quick note to Jonathan Doye, Professor of Theoretical Chemistry at Oxford, “…is there any recognition of the five-octahedral gap? I am not even finding any articles about it. In May, I started a little analysis: https://81018.com/geometries/ Are these five-octahedrons and their gap at all part of your studies?”

What’s its name? LITTLE DIAMOND, GEM, JEWEL? OR, DOES IT ALREADY HAVE A NAME? …FIVE TETRAS ON FIVE OCTAS ON FIVE TETRAS.
