Abstract: Let be a prime , and let be a primitive th root of unity. Let be the maximum number of consecutive units of the cyclotomic field . It is shown that , where is the maximum number of consecutive residues modulo , and the maximum number of consecutive non-residues modulo . This result implies that, for the primes under 100, is exactly 4 for (and possibly for the other primes as well). Another consequence is that .
