Perhaps samuel is mipsplepping the calculus method I mentioned here.

I have every right to make sport of samuel's avatar, and to at his ordering me not to. Freedom of speech, you know.

And if samuel wants to insist his avatar is a photo, I guess he must be, not a demon, but the serpent himself.

Perhaps you could tell us M53 and M54 so we could get a head start on verifying them....

Check it out.

Generates ALL 51 exponents in order, perfectly.

So do you agree that the output for M52 must be correct?

all i see is some random code, where is the formula? stop bluffing

Pay attention you dozy little twit. The code is a program which generates the formula.

I'm sorry, but that's too advanced for him to understand. You'll need to dumb it down about 10 grade levels.

Hey samuel, I suggest you read this page. It could give you some insight on coming up with a "formula" (maybe).

Default circuit

Hi, not sure if this is the right place to post this, but I have a conceptual design for a fast and relatively simple circuit that rather accurately predicts whether a prime mersenne exponent produces a mersenne prime. It's a 30-input NOR. For p>0, its output is always low (indicating composite). It's only wrong for 0 and the mersenne primes, known or unknown. That's only about a 1.1 ppm error rate, which is way more accurate than most lab measurements or design calculations. :)

Edit: a more efficient design gets rid of the error on zero input and reduces power consumption and cost, and easily scales to higher p. Inputs are opens or may be omitted; output is grounded.

Okay, how about some fancy math, say a polynomial, to improve the accuracy to the desired level? Nope; no polynomial can generate only primes.

(That's a good one, retina ;) An exercise for the OP, or for retina, or anyone with a predictor proposal:
Use a randomly selected subset of almost all the known mersenne primes to predict the rest of the set of known mersenne primes. How does your method fare for predictions yielding the excluded few?
Or not-so-randomly; if you had only up to M50 as input, how does it fare in predicting M51 correctly?

If anyone could provide a working predictor, I'd happily amend https://www.mersenneforum.org/showpo...04&postcount=5
The frequency difference for p mod 8 versus other values is intriguing.

their formula is obviously incorrect mine is accurate now for m1 to m51, so the law of mathematics if the formula gives us m1 to m51 then the 52 term must be m52, that is like the basic of mathematics how u not know

Read up about Lagrange interpolation. It is a real thing. It creates a degree n-1 polynomial for n input values. And it allows us to ask for values off the fitted curve.

But maybe the python code is too advanced for you to understand.
