WebProperties It was shown by Collins (1969) that it is an undecidable problem to determine, given a finite presentation of a group, whether the group is Hopfian. Unlike the undecidability of many properties of groups this is not a consequence of the Adian–Rabin theorem , because Hopficity is not a Markov property , as was shown by Miller & Schupp (1971) . http://marc-b-reynolds.github.io/quaternions/2024/05/12/HopfCoordConvert.html diy housewarming ideas
