#PythaShastri prime number sieve

1. Let current number be x.
2. Let x +1 be y.
Two variables needed.  x and y.
For any range prime number sieving do the following models:
1. Check divisibility of x by 2.
2. Check divisibility of x by 3.
3. Check divisibility of y by 4.
The above are the only methods needed.
Further steps are worked out.
By the way, I have registered copyright on two pi expressions.
( I don't like copyright or patents. But then . . . )

  2. I shall make use of Euler prime generating equation sorts.
    I shall then score 78.5 percent.

    1. I shall exactly use Euler prime generating equation.
      I shall use -n values.

    1. Let me give an example.
      33 to 40 range. Find primes.
      33. 3 multiple. Not prime.
      34. 2 multiple. Not prime.
      35. Try 36 for 4. Yes 4 × 3 ×3. Two 3 multiple. Not prime.
      36. 2 multiple. Not prime.
      37. Try 36 for 4. Not happening.
      Here I try 1+n squared. 1 + 6 squared. Prime.
      38. 2 multiple. Not prime.
      39. 3 multiple. Not prime.

  4. I used x - 1 for y.
    I used 1 + n = n squared in some fashion. Something something.
    Is 17 a prime? Yes indeed 1 + 16.
    10 and 26 eliminated because of even.
    Above 41 I shall use n + n squared + 41. I swear.
