It is well known that all of the prime cyclotomic polynomials and binary cyclotomic polynomials are flat, and the flatness of ternary cyclotomic polynomials is much more complicated. Let p<q<r be odd primes such that zr≡± (mod pq), where z is a positive integer. So far, the classification of flat ternary cyclotomic polynomials for 1≤z≤5 has been given. In this paper, for z=6 and q≡±1 (mod p), we give the necessary and sufficient conditions for ternary cyclotomic polynomials Φ pqr (x) to be flat.
