Imaginary quadratic number fields with class groups of small exponent Elsenhans, Andreas-Stephan Klüners, Jürgen Nicolae, Florin Algebra and Number Theory Let D<0 be a fundamental discriminant and denote by E(D) the exponent of the ideal class group Cl(D) of K=ℚ(√D). Under the assumption that no Siegel zeros exist we compute all such D with E(D) dividing 8. We compute all D with |D| ≤ 3.1⋅10²⁰ such that E(D) ≤ 8.
