As of now, the DIV LLR subproject is scheduled to stop at n = 9M. For comparison, 321 LLR is at n = 16M and continuing to at least n = 50M.
I feel it would be reasonable to continue DIV to beyond 9M. Some searcher has already located several primes with 4 < k < 50 and n > 9M. So why should PrimeGrid stop at n = 9M?
I think the immediate reason for the 9M is the sieving we have? There is a Proth sieve running, but I do not think it considers candidates with exponents n over 9M yet? The schedule says "currently sieving 6M-9M which will be sieved to 900P. We will then transition to 9M-12M which will be sieved to 1600P".
What I want to suggest here, is that we start an additional sieve for 4 < k < 50 and 9M < n < 18M or similar. If/when the 321 sieve is soon suspended, maybe it would make sense to substitute it with a DIV sieve?
(We could consider whether such a sieve should share the badge "PPS SV" with the existing sieve, in the same way the projects PPS, PPSE, MEGA, DIV all share one badge "PPS LLR".)
