Hello SeqFans,
following my former post, the same idea
could be applied to primes:
Pr = 0,11,2,3,1,7,4,10,9,8,12,5,...
Again, I guess, a permutation of 1,2,3,4,5,...+oo.
0 and 11 produce 101, a prime
11 and 2 produce 211, a prime
2 and 3 produce 23
3 and 1 produce 13
1 and 7 produce 17
7 and 4 produce 47
4 and 10 produce 401
10 and 9 produce 109
9 and 8 produce 89
8 and 12 produce ...
etc.
Best,
É.
