Tricky problem

How do i find the number of independent components of the Riemann curvature tensor in D space-time dimensions.

One is given that the Riemann tensor is an (2,2) irreducible rep of [itex] GL(4, \mathbb{R}) [/itex] and obeys Bianchi I

[tex] R_{[\mu\nu|\rho]\lambda}=0 [/tex]

Been trying this problem for 3 days and couldn't come up with a reasonable answer.

(1/12)*n^2*(n^2-1) where n=D.
