Abstract

We provide a list of possible torsion groups that can occur for a cyclic cubic field $K$ where the conductor of $K$ is between $1$ and $100$ . We were not able to rule out or prove the existence of: $ℤ ∕ 13 ℤ$ over cyclic cubic fields of conductor $63$ , $ℤ ∕ 18 ℤ$ over cyclic cubic field of conductor $9$ , or $ℤ ∕ 2 ℤ \times ℤ ∕ 14 ℤ$ over $K \subset ℚ (ζ_{63})$ isomorphic to $ℚ [x] ∕ ⟨ x^{3} - 195 x^{2} + 3267 x - 1 ⟩$ .
