If you are not familiar with the Flower of Life, it can be constructed as follows. Draw a circle. Find the verticies of an inscribed hexagon. For each such vertex draw a circle of that same size with that vertex as center. The pattern can be continued indefinitely with each circle having six circles passing through its center.
All this depends on the length of each side of the inscribed hexagon being equal in length to the radius of the circle. Is there a Platonic solid that would meet this criterion? That is, is there an N-D Platonic solid inscribed within an (N-1)-sphere with radius r such that the distance between neighboring verticies is r? I'm fairly certain this can't be done in arbitrary N, but N=3,4,8,or 24 might be possible.
