Quaternion group

    1. The problem statement, all variables and given/known data
    Obtain multiplication table for quaternion group.


    2. Relevant equations

    ##i^2=j^2=k^2=ijk=-1##
    3. The attempt at a solution

    I have problem with elements for example ##ji## in the table. For example when I have ##ij## I say
    ##ijk=-1## and ##k^2=-1## so ##ij=k##. But what in the case of ##ji##? I do not know how to obtain this result.

    What do you get if you post-multiply (ji) by (ijk)?
