An extension theorem for generating new families of non-congruent numbers
Lindsey Reinholz, Blair Kenneth Spearman, Qiduan Yang · Functiones et Approximatio Commentarii Mathematici · 2017
A technique for generating new families of non-congruent numbers by appending a tail of primes to extend known families of non-congruent numbers is presented. These new non-congruent numbers are comprised of arbitrarily many prime factors belonging to two or three odd congruence classes modulo 8.
