Abstract: Describing the group of units in the integral group ring is a famous and
classical open problem. Let 𝑆3 and 𝐶3 be the symmetric group of order 6 and a
cyclic group of order 3, respectively. In this paper, a description of the units of
the integral group ring ℤ(𝑆3 × 𝐶3) of the direct product group 𝑆3 × 𝐶3
concerning a complex representation of degree two is given. As a result, a part of
the conjecture which is introduced in (Low, 2008) and related to group rings over
a complex integral domain is resolved using representation theory.
