The prime is 1,013,908 digits long and will enter Chris Caldwell's The Largest Known Primes Database ranked 202nd overall.

The discovery was made by Kimmo Koski (Cinclus) of Finland using an Intel(R) Core(TM) i7-4790 @ 3.60GHz with 24GB RAM, running Microsoft Windows 10 Core Edition. This computer took about 1 hour 42 minutes to complete the primality test using LLR. Kimmo is a member of the Aggie The Pew team.

The prime was verified on 18 February 2017, 09:31:18 UTC by Alen Kecic (Freezing) of Germany using an Intel(R) Core(TM) i5-4219M CPU @ 2.60GHz with 8GB RAM, running Microsoft Windows 10 Professional Edition.
