This article describes the value (and the process used to compute it) of some homotopy invariant(s) for a topological space or family of topological spaces. The invariant is homology and the topological space/family is three-dimensional lens space

Statement

Homology groups with coefficients in integers

Let L(p,q) be the three-dimensional lens space with parameters p and q. The homology groups with coefficients in the integers are:

Hk(L(p,q),Z)={Z,k=0,3Z/pZ,k=10,otherwise

Note that the homology groups do not depend on q, even though the homeomorphism class, and the homotopy type, of the space depend on q. (There are some equivalence conditions on q under which we get homeomorphic spaces, and weaker equivalence conditions under which we get homotopy-equivalent spaces, but the homology groups coincide even when these conditions are violated).
