What is the largest Twin Primes of this form you can get?

Where P1, P2,...,Pn are the consecutive primes and Ps is the resulting Prime

Example:

Maybe this is the only prime of this form.

Hi;

How high did you go?

I went to

{2,3,5,7,...7919} with no new ones found.


In mathematics, you don't understand things. You just get used to them.
Of course that result can be rigorously obtained, but who cares?
Combinatorics is Algebra and Algebra is Combinatorics.

Hi bobbym

Kool, can you paste the number pairs?

Hi;

What number pairs?

I can paste anything you want as long as you make it clear what you want.

I see you went up to 7919 and found none. I thought you have found one, I think it would be impossible to find the others as the largest  twin primes which differ by 2 so far is having 200,700 digits

. So, finding a twin primes which differ by two and also a summation of consecutive multiplied primes  +- 1 could be impossible, I guess.

It might be impossible, I found the same result for your other thread. When researching your idea, I could find no mention of it in the literature.

I love to play with the numbers and usually I don't claim it is mine until it is proven a novel idea. Because it is kinda frustration to know someone else has found it. I think the generalized formulation could be written as P1P2..Pn+-(Pn-1)=Ps, where all of them are prime.
