A new prime has been discovered (pending verification) and has 5,269,954 digits.

It is 7 ·6 6772401 + 1 .

Although I am doubtful it was checked as a Proth Prime, it might be represented as such

[7*3**6772401* 2**6772401 +1 .

It is by far the largest Prime of 2019 and if verified it will rank as #18 in the list of Largest Primes kept by CC

Congratulations to Ryan Propper.

Edit: A Proth number is restricted to k k>2n N=k2n+1 so I ammend my previous statement.
