Abstract: Let $ C(X,G)$ denote the group of continuous functions from a topological space $ X$ into a topological group $ G$ with the pointwise multiplication. Some classes of SQ-pairs and properties of the corresponding topological group $ C(X,G)$ with the compact-open topology are investigated. We also show that the existence of a group isomorphism between groups $ C(X,G)$ and $ C(Y,G)$ implies the existence of a homeomorphism between $ X$ and $ Y$, if $ (X,G)$ and $ (Y,G)$ are SQ-pairs.
