Is there any good way to get the groups of order 16? I found 12 groups. But not getting remaining two. I found one article "Groups of order Sixteen Made easy", but his arguments are using something called cyclic extensions(Alas!! Is it necessary to use EXTENSIONS ?).</p> http://mathoverflow.net/questions/52912/groups-of-order-16/52919#52919 Answer by RDK for Groups of order 16 RDK 2011-01-23T05:29:55Z 2011-01-23T05:29:55Z <p>There is a book "Groups for Undergraduates" by John Moody, who has given classification of groups of order 16, without Extension Theory...he has used "Abelianization" process....it may be helpful....</p>
