Apophenia v.1
Prime sprial plotting software for square (Ulam) and related polygon prime number spirals. Allows multiple prime generating quadratic equations to be displayed simultaneously. Plot data and image files can be saved to disk for further analysis.
Prime Number Spiral v.8 59
The Prime Number Spiral (a.k.a. the Prime Spiral and the Ulam Spiral) is constructed as follows: Consider a rectangular grid. First, start with the central point and arrange the positive integers in a spiral fashion (anticlockwise).
