I spent the past 30 minutes making this.

Today marks the one-year anniversary of the current largest known prime number 2^136279841-1 being discovered!

Some #MersennePrime news: on December 26, 2017, Jon Pace of the Great Internet Mersenne Prime Search found that 2^77232917-1 was prime. It was the 50th *discovered* Mersenne prime, but on September 8th all double-check tests on Mersenne numbers below it have finished, officially confirming it to be the 50th Mersenne prime overall!

A #MersennePrime #math pattern I love is the Catalan-Mersenne number conjecture (https://en.wikipedia.org/wiki/Double_Mersenne_number#Catalan–Mersenne_number_conjecture):

2^2-1 = 3 (prime)
2^3-1 = 7 (prime)
2^7-1 = 127 (prime)
2^127-1 = 170141183460469231731687303715884105727 (prime)

Is 2^170141183460469231731687303715884105727-1 prime? It's so big it's unlikely, but you never know. We can only hope to find a factor of it: http://www.doublemersennes.org/mm127.php

Learned about the Great Internet Mersenne Prime Search (GIMPS) this morning. There's just something about prime numbers, I think I'll add my computer to the search this evening.

Mersenne primes are of the form 2^p - 1, and currently the largest known prime is a Mersenne prime found by GIMPS. Exciting stuff!

2⁷⁴²⁰⁷²⁸¹-1 is the 49th *discovered* Mersenne prime, discovered by Curtis Cooper at the University of Central Missouri in early 2016. All numbers of the form 2ᵖ-1 (where p is prime) must be double-checked to ensure no primes are missed.

Good news: there's only 7 more double-check tests to go until 2⁷⁴²⁰⁷²⁸¹-1 is *officially* proven to be the 49th Mersenne prime *overall*!

A fun #math project I found: can we say all 41,024,320 digits of the largest known prime number before a larger prime number is discovered?

You get assigned a 419-digit exerpt of the prime for you to say on video, then everyone's videos saying their digits are put in a row so everyone says the prime number in full.
