I propose algorithm for finding twin primes:
Positive integers which do not appear in all four arrays $A1(i,j)=6i^2+(6i−1)(j−1)$, $A2(i,j)=6i^2+(6i+1)(j−1)$, $A3(i,j)=6i^2−2i+(6i−1)(j−1)$ and $A4(i,j)=6i^2+2i+(6i+1)(j−1)$
| 6 11 16 21 ...|
A1(i,j) = | 24 35 46 57 ...|
| 54 71 88 105 ...|
| 96 119 142 165 ...|
|... ... ... ... ...|
| 6 13 20 27 ...|
A2(i,j) = | 24 37 50 63 ...|
| 54 73 92 111 ...|
| 96 121 146 171 ...|
|... ... ... ... ...|
| 4 9 14 19.. |
|20 31 42 53...|
|48 65 82 99...|
A3(i,j)= |88 111 134 157...|
|... ... ... ... |
| 8 15 22 29 ..|
|28 41 54 67...|
A4(i,j)= |60 79 98 117..|
|104 129 154 179...|
|... ... ... ... |
are index $k$ of twin primes in the sequences $S1(k)=6k-1$ and $S2(k)=6k+1$.
So twin primes are:
$ 5, 7(k=1)$ .. $11, 13(k=2)$ ..$17, 19(k=3)$ .. $29, 31(k=5)$....
Is proposed algorithm for finding twin primes well-known?
