Rectified decayotton

The rectified decayotton, or reday, also called the rectified 9-simplex, is a convex uniform polyyotton. It consists of 10 regular enneazetta and 10 rectified enneazetta. Two enneazetta and 8 rectified enneazetta join at each octaexic prismatic vertex. As the name suggests, it is the rectification of the decayotton.

It is also a convex segmentoyotton, as enneazetton atop rectified enneazetton.

Vertex coordinates
The vertices of a rectified decayotton of edge length 1 can be given in ten dimensions as all permutations of:


 * $$\left(\frac{\sqrt2}{2},\,\frac{\sqrt2}{2},\,0,\,0,\,0,\,0,\,0,\,0,\,0,\,0\right).$$
