which ones are suppose to match. cause i dont see any that do. Also for the group table of Z3xZ2, what is the order that the elements are suppose to go in? For instance i did (0,0), (0,1), (1,0), (1,1), (2,0), and (2,1) in that order for the row side and column side, then filled in the group table. Also what is another way to check if they are isomorphic without making tables?
The matching ones are Z6 and Z2xZ3.
The order doesn't matter, it's a table, it's just a way to organize data.
From what I understand your best bet is to match up the tables. If you want some more high-tech stuff, it will require more machinery which you don't seem to be comfortable with just yet based on your questions to-date. If you want to try, you can do what I suggested in my last post.
