# Provisional 46th Mersenne prime M42643801 supports Collatz conjecture

On August 3rd, 2017 our “3007 Collatz Tester for Mersenne Primes” (the improved version of “3000 Collatz Tester”) tested the provisional 46th Mersenne prime M42643801 for being in agreement with Collatz conjecture and supported it.

M42643801 required 573966881 steps to get from 1.70*1012837063 to 1. In the process the sequence took 85287601 first steps to expand by 8.13*107509200 times.

Full statistics for M42643801 Collatz sequence is presented below.
