This says no one else has it.

That exponent doesn't need P-1 done, so the server wont register a P-1 assignment.

You are welcome to do it though. The server will accept your results as long as your bounds are larger than the previous P-1 bounds.

Thanks....

I understand it already has DC done and some P-1 but with somewhat low bounds.

As a personal project over the last year or so I have been cleaning up lower exponents with P-1 with poor bounds (I know there are a few others doing similar work and we are careful not to step on each other's toes).

I have similarly done P-1 recently on thousands of exponents in the 11M-14M range and 40M range with no trouble getting the assignments.

I chose exponents under 50M where EXP/B1 > 120 and EXP/B2 > 9.
The exponents getting rejected have ratios around 180 and 9-10 respectively.

This is not based on any solid P-1 math but it seems to be a quite a bit short of optimum bounds (though I do understand these are also based on the current TF level). I looked for the higher ratios so as to give me a manageable list to work on.
