    Let G be a 2-dimensional connected, compact Abelian group and s be a positive integer. We prove that a classification of s-sheeted covering maps over G is reduced to a classification of s-index torsionfree supergroups of the Pontrjagin dual Ĝ. Using group theoretic results from earlier paper we demonstrate its consequences. We also prove that for a connected compact group Y: (1) Every finite-sheeted co vering map from a connected space over Y is equivalent to a covering homomorphism from a compact, connected group. (2) If two finite-sheeted covering homomorphisms over Y are equivalent, then they are equivalent as topological homomorphisms.
