There is a known 42 bit factor for M13,029,749, with trivially small P-1 bounds sufficient, or very brief TF. https://www.mersenne.ca/exponent/13029749
Oliver Kruse's PRP run in progress is a waste of time. https://www.mersenne.org/report_expo...exp_hi=&full=1
It's also much too small an exponent for Mp52*, since everything up to nearly 108 has already been tested at least once, and to nearly 54M twice, while the guess is only ~13M, and Mp51* has exponent 82,589,933. Mp52*'s exponent must exceed ~54M and probably 100M.

(Maybe 13029749 was a pre-coffee guess?)
