A Note on twin primes and the modular ring Z 6
J. V. Leyendekkers, Anthony G. Shannon · International Journal of Mathematical Education in Science and Technology · 2002
The modular ring ℤ6 defines integers via (6r i + (i − 3)) where i is the class and r i the row when tabulated in an array. Since only Classes 26 and 46 contain odd primes, this modular ring is ideally suited to the analysis of twin primes. The calculations are facilitated by the use of the right-end digit (RED) technique.
