HNY! May the primes keep being discovered and the PRPs be proved. Most of all let there be a new Mersenne prime in 2021

It is also 2020219, as if transitioning from 2020 to 2021

Thanks for the gift, and Congrats on the new find.

20201231 still not factored....I guess Covid is the cause

20210101 has 2 factors:
92966464; k=23
802381429903; k=3x13x509
