English: D6 roots projected to the hull of the H3 Icosadodecahedron using:

The specific basis vectors are:

x = {1, φ, 0, -1, φ, 0}

y = {φ, 0, 1, φ, 0, -1}

z = {0, 1, φ, 0, -1, φ}

There are 60 vertices with 480 edges of 6D length Sqrt[2], with 30 vertices and 120 edges on the Hull. There is another Icosadodecahedron scaled at the Golden Ratio on the interior.
