Abstract
Let and be finite groups of order where is odd. We say the pair is Hopf-Galois realizable if is a regular subgroup of . In this article we give necessary conditions on (similarly ) when (similarly ) is a group of the form . Further we show that this condition is also sufficient if radical of is a Burnside number. This classifies all the skew braces which has the additive group (or the multiplicative group) to be isomorphic to , in this case.
