comment Galois group of $x^5-x+1$ over $\mathbb{F}_7$
That doesn't seem right. $\phi_2$ is the permutation $(45)$ and $\phi_3$ is $(345)$, so together they generate $S_3$.

comment Expected frequency of most frequent die roll
Say the partition is {7,4,4,4,1,1}, so n=21. For the 7-frequency event we have mC1 choices, for the three 4-frequency events we have (m-1)C3 choices, for the two 1-frequency events we have (m-4)C2 choices. Then we arrange the events with 21!/(7!4!4!4!1!1!).

comment Expected frequency of most frequent die roll
The question is whether there is a closed form for E(n,m).
