Hmmm, OK let's redo that analysis:
In the range 33219281  33300000 there are:
4702 prime exponents
2978 of which have factors
1724 do not have factors
As before, of those 1724, there are 30 in LUCAS_V.TXT (verifiedgood results, matching doublechecks) and there are 1459 in HRF3.TXT (only one LL test, or nonmatching doublechecks). There are no results in LUCAS_V.TXT or HRF3.TXT for 33.2M less than 33219281.
So 235 exponents in this range have no known factor and never had an LL test returned.
Now, the current status.txt (assigned exponents) shows 231 exponents currently assigned in this range. Again, there are no assignments for 33.2M less than 33219281.
However, of these, 5 assignments are for exponents that have already been LL tested at least once:
33222047
33228563
33234007
33285839
33298957
That leaves 9 exponents that have never been factored or LL tested and are not assigned by Primenet:
33229069
33236519
33238477
33240079
33243181
33249397
33255259
33290479
33297029
These 9 could be manual tests or reserved by Glucas / Mlucas. Or perhaps truly never assigned yet to anyone?
