Concerning Prime[N] modulo 3
I strongly suggest to you, primes split
evenly between
having a residue of 1 and 2 modulo 3.
I checked to 2^22 and it seems to be so.
the sequence
{of Prime[N] modulo 3}
is
2, 1, 2, 1, 2, 1, 2, 2, 1, 1, 2, 1, 2, 2, 2, 1, 1, 2,
1, 1, 2, 2, 1
if 1
tends to be followed by 2 and 2 by 1...
I looked at the four possibilities
p(1->1)
p(1->2)
p(2->1)
p(2->2)
This is graphed as a function of N at
http://physics.technion.ac.il/~rutman/images/primes_mod3_remainders.jpg
{note x-axis off by 2, namely final value is at x=22=log2(N) }
It has an interesting structure. Note bump at N=2^12.
Also values p(1->2) and p(2->1) seem to converge to 0.2766 while values values p(1->1) and p(2->2) converge to 0.2233. Or do they really converge at very large N to 0.25 each? Its very slow convergence if so.
