CONSTRUCTION OF T-MATRICES OF ORDER 6m+1

2017 · Far East Journal of Mathematical Sciences (FJMS)

In this paper, we prove the necessary and sufficient condition for an integer n = a^2+3b^2. Consequently, every prime power 6m+1 has a representation of the form a^2+3b^2. Then we show how to construct T-matrices …
