now it works, thanks...
one more thing: the link in the cells of the table which automatically fills the form contains min/max values which are both one to high

The fourth factor is the product of the second and third. Probably this problem occurs because the Prime95 application executing on my computer submitted the product of the second and third prime numbers while running the P-1 algorithm.

I have removed the offending factor, but I am not yet certain how or why it was allowed into the database in the first place. Further investigation is required.

Small cosmetic thing. On the tf1G.php page, the counts in the Assigned column can go negative. This seems to happen when an exponent is reserved for factoring more than one bit depth in one go, say 67 to 69, and then the results are reported in two parts, first 67 to 68, and then 68 to 69.

Anyway all is correct after the daily run so it's just a temporary nuisance.

Yes, that can happen as you describe. For speed of display the counts shown on the page are from a cache table that stores the numbers assigned and available, and when results are reported and accepted the count is updated. The side effect is as you describe: if a result is submitted and accepted more times than the exponent is assigned (multiple bit levels reported for a single assignment, or results reported for unassigned exponents) then the count can temporarily end up negative. The data is rebuilt every night and currently takes about 16 minutes to rebuild.

Default Exponent status report "Needs double-check" erroneously

Recently the exponent status reports seem to give "needs double-check" despite matching LL residues... e,g. https://www.mersenne.org/report_expo...6851641&full=1 and https://www.mersenne.ca/exponent/46851641

Thanks. Somehow you caught the one exponent in the database that was out of synch.
I have also added some code that (I hope) should prevent this in the future.

I think that the problem might be a bit more general than that, James. It seems to have been happening for a number of days, but not quite sure how long. Several of my recent LL DCs seem to have the same flaw, e.g. 46818137 & 46865327, though further back 46699987 on 14 March is OK.
