Summary

Detail Description:
The 8 axes are shown with locators labeled A-H. The 128 vertices are a subset of the E8 group of even (half-integer) permutations. The number of vertices in each column represents rows in Pascal's triangle, being 1:7:21:35:35:21:7:1 in the case of a 7-cube. The 448 edges of unit length have colors that can be varied based on their projected edge positions. The vertex color is varied by overlap counts. Specifically:
vertices={color=overlap,count},...,Total
{{purple=1,32},{black=2,24},{red=3,30},{green=4,32},{blue=5,10}},128

vertices InView={{color=overlap,count},...,Total
{{purple=1,32},{black=2,12},{red=3,10},{green=4,8},{blue=5,2}},64

The 2 projection vectors are:
H={1/Sqrt[7], 1/Sqrt[7], 1/Sqrt[7], 1/Sqrt[7], 1/Sqrt[7], 1/Sqrt[7], 1/Sqrt[7], 0}
V={-(3/(2 Sqrt[7])), -(1/Sqrt[7]), -(1/(2 Sqrt[7])), 0, 1/(2 Sqrt[7]), 1/Sqrt[7], 3/(2 Sqrt[7]), 0}

doCubePascal@n_ := (
H = Normalize@Join[Array[1 &, n],Array[0 &, 8 - n]];
V = Normalize@Join[Table[i, {i, -(n - 1), n - 1, 2}],Array[0 &, 8 - n]];)
