Also can be written as (5798^4201+1)/5799. The N-1 is factored at 28.09% so CHG was likely used.

U(5797,-5798,4201) 28.097% Factorization of N-1, along with Primo certificate of a P1740 factor, can be found at http://factordb.com/index.php?id=1100000001174685072 CHG input/output files available at https://www.mat.univie.ac.at/~chen/5798_4201.in and https://www.mat.univie.ac.at/~chen/5798_4201.out

Verification data:

The Top 5000 Primes is a list for proven primes only. In order to maintain the integrity of this list, we seek to verify the primality of all submissions.  We are currently unable to check all proofs (ECPP, KP, ...), but we will at least trial divide and PRP check every entry before it is included in the list.
