Rectified pentacontahexapentacosiheptacontahexaexon

The rectified [entacontahexapentacosiheptacontahexaexon, or rolaq, also called the rectified 231 polytope, is a convex uniform polyexon. It has 56 rectified icosiheptaheptacontadipeta, 126 demihexeracts, and 576 rectified heptapeta. 2 demihexeracts, 6 rectified icosiheptaheptacontadipeta, and 6 rectified heptapeta join at each rectified hexateric prismatic vertex. As the name suggests, it is the rectification] of the [[pentacontahexapentacosiheptacontahexaexon.

Vertex coordinates
The vertices of a rectified pentacontahexapentacosiheptacontahexaexon of edge length 1, centered at the origin, are given by:


 * $$\left(\frac{\sqrt2}{4},\,\frac{\sqrt2}{4},\,\frac{\sqrt2}{4},\,\frac{\sqrt2}{4},\,\frac{\sqrt2}{4},\,\frac{\sqrt2}{4},\,±\frac32\right)$$ and all even sign changes of the first six coordinates
 * $$\left(±\frac{\sqrt2}{2},\,±\frac{\sqrt2}{2},\,±\frac{\sqrt2}{2},\,±\frac{\sqrt2}{2},\,0,\,0,\,±1\right)$$ and all permutations of first 6 coordinates
 * $$\left(\frac{3\sqrt2}{4},\,\frac{3\sqrt2}{4},\,\frac{\sqrt2}{4},\,\frac{\sqrt2}{4},\,\frac{\sqrt2}{4},\,\frac{\sqrt2}{4},\,±\frac12\right)$$ and all permutations and even sign changes of the first six coordinates
 * $$\left(±\sqrt2,\,±\frac{\sqrt2}{2},\,±\frac{\sqrt2}{2},\,0,\,0,\,0,\,0\right)$$ and all permutations of first 6 coordinates
 * $$\left(\frac{\sqrt2}{2},\,\frac{\sqrt2}{2},\,\frac{\sqrt2}{2},\,\frac{\sqrt2}{2},\,\frac{\sqrt2}{2},\,\frac{\sqrt2}{2},\,0\right)$$ and all even sign changes of the first six coordinates
