It's more like a heuristic (or estimate even), not a formula. Again, don't take it too seriously...

I will admit, the most recent Mersenne primes fell below average of this estimate, perhaps M52 will fall above average this time... or maybe not.

Curiously, I discovered this so called "formula" is also good for estimating the next prime of the form k*b^n+-1 (assuming there exist an infinite number of primes of this form):

Here you are, given a completely relevant post in a subject about which you care passionately, and you are too stupid even to try to work out what it means. I don't read lots of things --- my Python is very poor indeed --- but I did at least make an attempt to read it.

As well as uneducated, you didn't even try to run the program and examine its outputs. Is that really the behaviour expected of some one as smart as you claim to be?

Being a prick who causes nausea?

Ignorance is no excuse. (Note there is a difference between ignorance and stupidity. Often one can lead to the other, but it is not a given.) As Paul pointed out, you should at least attempt to figure it out. Also, for you it would be good to learn python. You can knock together some code to do number crunching with it. It is fairly human readable, widely used (so you can find the work of others and borrow it), and free. Any budding math scholar should have that in their tool kit.

Your argument that predicting all of something up to a certain point, does not consist of a proof. (Look up the early history of Mersenne primes to see this in action. There are also other sequences that fail after a large number of elements that conform [if you can't find examples, ask and I am sure that someone here can point you to a few].) A proof is a logical, mathematically defensible reason. It is not a guess, not just a bunch of data, nor an idea or feeling. It is a logical string of knowns that establish the validity of the thing sought to be proved. Don't you remember geometry and working through proofs? That same rigor applies to math and number theory.

BTW, are you trying to deny Paul the freedom of speech that you are trying to claim you have?

I find it extremely funny that a poster whose avatar appears to be a snake, doesn't know python.

I don't know python, either. But I don't have to in order to know what the program is doing. The key phrase "Lagrange interpolation" outside the code tells anyone who bothers to read the post what the program is supposed to be doing. I do know what Lagrange interpolation is.

If samuel doesn't, and hasn't bothered looking it up -- or didn't bother reading the post in the first place -- he obviously isn't really interested anyway.

Whatever it is, it's a long ways from any sort of mathematical proof, but maybe he thinks it qualifies as this: https://en.wikipedia.org/wiki/Mathematical_induction

And like other high order polynomial fits, it's notoriously unreliable in extrapolation beyond the data bounds. And it can also be pretty wild between the sorted data points.

Hehe. Well according to samuel ...

... I have found M52.

It seems the type of polynomial doesn't matter. Just any polynomial will do. As long as f(1)=M1, etc. then you're good to go.
