couple fo things:
(i) what happened with my LaTeX? e.g. [itex]R_{abc}^{d}[/itex]. how do i get the d to come after abc?
(ii) to prove that [itex]R_{abcd}=R_{cdab}[/itex] how do i switch the ab with the cd?
(iii) i dont understand your anti symmertrisation thing. surely for the n=3 case, [itex]|S_n|=3!=6 and so it should be 1/6 and then there will be 6 terms in the brackets? also how do u decide the sign of a permutation?
