But for ${\mathbb Z}/2$ coefficients, for $S_4$, you can find in Adem & Milgram, for $D_n$, probably it is also in Adm-Milgram, but it is certainly in MacLane. For $S_5$ and $A_5$, it follows from the computation of $S_4$ and $A_4$ if you only care about mod $2$ coefficient, but it is unlikely to find an "explicit" expression for these. Well, probably you can look Kechagias for cohomology ring of $S_n$ in general. Anyway, the ring structure, in these case, is known completely (for mod 2 coefficients). | |
