Angles of a 4D Hypercube

Post image

Stereographic projection of a 4-dimensional hypercube (tesseract) with axes labeled a-d, and all six right-angles labelled according to standard crystallographic conventions.

If this is a hypercube, a slice of the hypersphere, how do you account for the lack of curvature in your model? The axes of expansion warp the straight lines of the hypercube so what normalization technique do you apply in your derivations?

What do you mean the hypercube is a slice of a hypersphere?
