Is there a reference, where the proof is carried out in detail?
• On September 3 Dario Weißmann left comment 2794 on tag 00DV
No, I think the result is correct as stated. Why your example does not work: what is your finite $N'... • On September 2 Kong Bochao left comment 2793 on tag 00DV I think M finite is needed, just consider the third version, let$M=N\bigoplus I$then$M/N\backsime...
