### Geometry of the Binary Tetrahedral Group in SU(2)

# Edges

There are three possible distances between elements of the
binary tetrahedral group (not counting 0 and pi): They are

g = pi/3

p = pi/2

v = 2*pi/3.

The distance between points x and y in the group is their
angular distance, which can be computed as arccos(x.y).
These distances are given in the Table
of Distances. (Browser's note: this table displays
correctly in Netscape, but may not for you.)
