The AbelianInvariants method, utilized for establishing correspondence between an abelian group and its canonical form, experiences sluggish performance when isomorphism is employed. At times, the implementation based on algebraic proof does not yield the most efficient results.
For a potential enhancement, revisiting the Quotient of abelian groups and refining the representation of cosets may help to resolve challenges encountered during the computation of cohomologies.

When computing H2(C2xC2, C2xC8), some errors occur in cosets and many representatives are unnecessary.
