I tried to get a PRP-CF-D assignment of this via the manual assignment page. PrimeNet didn't want to give it to me.

PFGW Version 4.0.0.64BIT.20190528.x86_Dev [GWNUM 29.8]

No factoring at all, not even trivial division
                                        
Lucas testing on x^2 - 3*x + 1 ...
Is Lucas PRP!

I took liberty to let Lifchitz PRP Top site know.
It is in position #3 now.

(2^10443557-1)/37289325994807 is Fermat, Lucas and Frobenius PRP! (P = 5, Q = 3, D = 13) Time : 80331.237 sec.

This would be a new record. The previous record-holder was M7,313,983
M10,443,557 was 344th.

345th is M3307, as reported here and here

The cofactor was certified in factordb on July 19th.

The 346th fully-factored or probably-fully-factored Mersenne number with prime exponent (not including the Mersenne primes themselves) is M1999.

The most recent factor (49 digits) was found by Ryan Propper on September 02 and the cofactor was certified to be prime by anonymous and verfied by FactorDB.
