A379643 - cp's OEIS frontend

A379643 List of x coordinates of prime numbers in a Cartesian grid, where the first prime 2 is placed at the origin (0,0) and the second prime 3 at (1,0). For the n-th prime prime(n), n >= 3, take a unit step in the direction (prime(n)-3)*45 degrees counterclockwise from the positive x-axis.
