    Genetic code of Klein four-group

    Hi,

    I've the following task: Find genetic code of Klein 4-group.
    I don't know how can I do this
    I know that the answer is: A_4=gr({A,B}||A^2=B^2=1, AB=BA).

    Any help will be highly appreciated.

    It seems like you people call "genetic code" to what most mathematicians, and group theorists among them, call "presentation of a group".

    That's thus correct: what you wrote is a presentation for the Vier gruppe, but if you haven't yet studied this stuff it'll be pretty hard to explain

    you how this thing works in this forum...you better go to some combinatorial group theory group book,

    say Schupp's, or Magnus' ...
