Euclidean 3-space is the most important example of a 3-manifold, as all others are defined in relation to it. This is just the standard 3-dimensional vector space over the real numbers. A 3-sphere is a higher-dimensional analogue of a sphere. It consists of the set of points equidistant from a fixed central point in 4-dimensional Euclidean space. … Web$\begingroup$ Well, there are other spherical 3-manifolds besides lens spaces and the Poincare dodecahedral sphere ... Moreover, the double branched cover of a knot is always a rational homology sphere. 3-manifolds with Heegaard genus 2 are always branched covers over the 3-sphere with branch set a knot or link. $\endgroup$ – Danny Ruberman.
