For quadratic number fields F = Q(√2pl … pt-1 ) with primes pj ≡ 1 mod 8, the authors study the class number and the norm of the fundamental unit of F. The results generalize nicely what has been familiar for the fields Q(√2p) with a prime p ≡ 1 mod 8, including density statements. And the results are stated in terms of the quadratic form x2 + 32y2 and illustrated in terms of graphs.
