COMMENTS

We are in 3D. Here the polytoothpick is a Ktoothpick. The Ktoothpick has 4 components or line segments, a central point and 4 endpoints, as a tetrapod but without volume. The Ktoothpick endpoints coincide with the vertices of a regular tetrahedron.
It appears that this is a threedimensional version of A160120, but with Ktoothpicks, not with Ytoothpick.
The first differences are in the entry A177241.
Question: Is this the same as A116520? (To answer the question we need a program because the structure is hard to visualize).
