Abstract
The characteristics within modular rings of the integer three are discussed. This integer has unique row structures in modular rings which appear to underlie restraints on various aspects of triples, particularly the factors and powers structure of the components. The function N = xm + 2n, with m even and n odd but x not divisible by 3, always has 3 as a factor, and a majority of elements of the sequence of triangular numbers {NT} are such that 3|NT. The modular ring Z3 and the distribution of primes within its structure are also discussed.
