Tidy up. Slightly better 1st image as per suggestions. |

Lines in image; are they significant to prime numbers if so how?
@WillSawin, I think I get the general idea but small correction; $P_{i}$/6 is not always $\pm1/3$ + some integer. Ex. 11/6 = 1+5/6. |

Lines in image; are they significant to prime numbers if so how?
Hi @WillSawin. I want to accept this answer but your argument is not completely clear to me. Proof omitted, it's this?: For any prime number $P_{i}$, and some other +ve number d < $P_{i}$, there exists another number M < $P_{i}$ s.t. $P_{i}$/M = d + r where r element of $\pm{1/d,2/d,...,(d-1)/d}$. So for example for $P_{i}$=23, and d=4 we have 23/8 = 4-1/8. This leads to, where at say $\pi/2$ rads for each prime number there is only a small set of possible offsets from that vector the point can lie on $\pm{-1/4,-2/4-3/4,1/4,2/4,3/4}$, which gives the impression of a contour. |

@jmc I've uploaded the original image, and full code in PHP. I used gnuplot to do the initial plot then GIMP to apply the Gaussian smoothing. I'll try one with a bigger radius and upload if it turns out. |

Can one measure the infeasibility of four color proofs?
True it is O(1) in Big-O notation, but Big-O is not a very helpful measure of complexity in this example. |
