The sieve of John Fullspeed must either
1) Do something useful that is different than finding prime numbers (and do it in a way not obviously equivalent to someone else's way of doing it)
or
2) Find prime numbers in a way that is not obviously equivalent to one of the known sieves.

If you want to do either, you will need to carry out Richard Silverman's advice, and not just the part directed to you. That famous professor you mentioned in another thread might also be able to give you some pointers, or help you get a degree in mathematics.

The third, more likely possibility is that you implement eratosthenes sieve better than others. It's still a rough task; begin by studying jasonp's code and others.

1- Do something new: I begin by creating a List with all the primed
not 2 < x < n

2- I remove composite value of my list not the multiple
n
3- My sieve go speeder that all the actual sieve for a technical reason not because a better implementation..?

My sieve is especial good for twin research and Sophie Germain it gives strong candidates ((not all the primes)
It create a twin mask that you can use starting from arbitrary number

You need less tha1 second to find candidats
and less 1 second to says if is a twin of a SG.

Is It a new sieve ora sppeder version of etastho...
The suestion is tha: well qualify the method

John

It's funny to laugh of handicap but be careful tomorrow it's can be you who choice a wheelchair (with a doc i french size 6)
I ithink that the artificial intelligencer can do nothing for you: try with the
monkeys

You prefer be Blind or Deaf? No problrm for me me I am the two...

Please keep in mind that English is not his first language; His English
