Chebyshev’s bias test range increased to 10^16

We further expanded Chebyshev’s bias test range 10 times to 1016. At the first stage, the tests will be run up to 5*1015. Expected time to complete the first stage – November, 2018.

Last Chebyshev’s bias data available in our repository

The last Chebyshev’s bias data became updated and available in our repository.

Provisional 50th Mersenne prime M77232917 supports Collatz conjecture

On March 17th, 2018 our “3007 Collatz Tester for Mersenne Primes” (the improved version of “3000 Collatz Tester”) tested the provisional 50th Mersenne prime M77232917 for being in agreement with Collatz conjecture and supported it. Continue reading

On December 27, 2017 our “4000 Chebyshev Bias Tester” completed testing all primes up to 10*1014  and found 3 first and previously unknown sign-changing zones for ∆{24;17,1}(x), where the value of ∆{24;17,1}(x) equals to -1. Continue reading

New sign-changing zones for ∆{24;13,1}(x) in Chebyshev’s bias found

On December 20, 2017 our “4000 Chebyshev Bias Tester” completed testing all primes up to 10*1014  and found 5 new and previously unknown sign-changing zones for ∆{24;13,1}(x), where the value of ∆{24;13,1}(x) equals to -1. Continue reading

Data on first sign-changing zone for ∆{8;7,1}(x) in Chebyshev’s bias included into OEIS

As we reported before, on November 20, 2017 we submitted two our sequences for registration with OEIS. The sequences fully defined the first found sign-changing zone for ∆{8;7,1}(x) in Chebyshev’s bias. Continue reading

Number of steps in Collatz sequence for Mersenne primes from 46th to 49th published in OEIS

On November 14, 2017 our data on number of steps in Collatz sequence for Mersenne primes with the provisional index from 46th to 49th were included in OEIS as a comment to A181777. Prior to this A181777 contained information up to the 45th Mersenne prime only. Continue reading
