Unity High School competes in the West Central Conference and is a member school in the Illinois High School Association. The UHS mascot is the Mustang, with school colors of maroon, white, and Columbia blue. Due to their small enrollment, they combine for football with Payson-Seymour High School. [2] [4] [5]
The group {1, −1} above and the cyclic group of order 3 under ordinary multiplication are both examples of abelian groups, and inspection of the symmetry of their Cayley tables verifies this. In contrast, the smallest non-abelian group, the dihedral group of order 6 , does not have a symmetric Cayley table.
The multiplicative identity 1 and its additive inverse −1 are always units. More generally, any root of unity in a ring R is a unit: if r n = 1, then r n−1 is a multiplicative inverse of r. In a nonzero ring, the element 0 is not a unit, so R × is not closed under addition.
The product and the multiplicative inverse of two roots of unity are also roots of unity. In fact, if x m = 1 and y n = 1, then (x −1) m = 1, and (xy) k = 1, where k is the least common multiple of m and n. Therefore, the roots of unity form an abelian group under multiplication. This group is the torsion subgroup of the circle group.

The sum of the entries along the main diagonal (the trace), plus one, equals 4 − 4(x 2 + y 2 + z 2), which is 4w 2. Thus we can write the trace itself as 2w 2 + 2w 2 − 1; and from the previous version of the matrix we see that the diagonal entries themselves have the same form: 2x 2 + 2w 2 − 1, 2y 2 + 2w 2 − 1, and 2z 2 + 2w 2 − 1. So ...
