Let h_n denote the class number of Q(2 cos2π/2ⁿ+2) which is a cyclic extension of degree 2ⁿ over the rational number field Q. There are no known examples of h_n > 1. We prove that a prime number ℓ does not divide h_n for all n < 1 if ℓ is less than 10⁹ or ℓ satisfies a congruence relation ℓ ≢ ± 1 (mod 32).
