A **spherical 3-manifold** is a type of three-dimensional manifold that is topologically equivalent to a quotient of the 3-dimensional sphere \\( S^3 \\) by a group of isometries (which preserve distances). More formally, a spherical 3-manifold can be described as a space of the form \\( S^3 / G \\), where \\( G \\) is a group of finite isometries of the 3-sphere.
