Minus Primality Test Formula

Primality Test Formula
We can determinate if one number is prime with the modulo operation.

I don't understand this part of the paper and to what number do I raise it to for the order of the derivative is it a random number?

Quote:
You need to increase the order of the derivative until the bound will be a little higher
of our number in this case the bound is 350148585 (the number in green) and our
number is (294662569) that is a little bit under this bound.
Also am I trying to solve for x?
(2 (-2 + 3 x^(2/(2*m))))/(3 x^((n)/(2*m))

Seems like the long way around the barn, given that the pdf states finding it prime in 30 seconds while https://www.alpertron.com.ar/ECM.HTM does it in under 1 second including internet delays.

Just a big pile of bullshit, from the beginning to the end. "If some number mod an even number is even, then you have to read another paper of mine, to see how to test if that's prime". Breaking news, an odd can't be even mod even. If that happens, your number is even and you don't need any formula. Your conclusion at the end of the document: "Conclusion: I lost 30 seconds of my life testing if that number was prime". My conclusion after reading it: "I want them back".

The bound (the number in green) raise with the order of the derivative. For example if you want to test 10001 and the 40th derivative gives you a bound of 9001 you need to increase the order of the derivative.

I also tried to solve for x but I didn´t found anything interesting

Default Primality Test Formula

I understand now your question.
I dont study deeply the relation between the bound and the order of the derivative. So take like a rndom number that you must increase to a number bigger than the number to test
