# 45th Mersenne prime M37156667 supports Collatz conjecture

On July 31st, 2017 our “3007 Collatz Tester for Mersenne Primes” (the improved version of “3000 Collatz Tester”) tested the 45th Mersenne prime M37156667 for being in agreement with Collatz conjecture and supported it.

M37156667 required 499902411 steps to get from 2.02*1011185271 to 1. In the process the sequence took 74313353 first steps to expand by 6.03*106542964 times.

Full statistics for M37156667 Collatz sequence is presented below.
