Who solved this?
editThis article is missing one of the most basic facts: who proved this was undecidable, and when? Was it Novikov in 1955, when he proved the word problem was undecidable? --Dylan Thurston (talk) 01:02, 31 March 2016 (UTC)
There seems to be confusion between this and NP-intermediate, which implies that Group Isomorphism is not only decidable, but no worse than NP-hard. 130.126.255.15 (talk) 20:00, 1 June 2016 (UTC)
This article talks about finite _presented_ groups, while group isomorphism for finite groups is decidable and in NP. This is probably meant by the NP-intermediate article. --138.246.2.252 (talk) 12:03, 5 October 2018 (UTC)
