abelian
How many different non-isomorphic Abelian groups of order 4 are there? 2 3 4 this is already discussed here https://gateoverflow.in/1219/gate2007-21 doubt 1 - here how do we ensure that the splits formed are abelian groups ? doubt 2 - if order of the group can be prime factorised then its sure to be abelian ? doubt 3 - how is non isomorphism proved in the solution?
