Let      A A       be an abelian      p p      -group having all of its finite Ulm invariants nonzero. Let      C C       be a countable direct sum of cyclic      p p      -groups such that for each nonnegative integer      n n      , the      n n      th Ulm invariant of      C C       is zero if the      n n      th Ulm invariant of      A A       is finite. Then for all reduced abelian groups      G G      ,      Tor ( G , A ) ≅  Tor ( G , A ⊕  C ) {\operatorname {Tor}}(G,A) \cong {\text {Tor}}(G,A \oplus C)      .

Abelian 𝑝-groups 𝐴 and 𝐵 such that 𝑇𝑜𝑟(𝐴,𝐺)≅𝑇𝑜𝑟(𝐵,𝐺), 𝐺 reduced
