Description - Prime Number Spiral
The Prime Number Spiral (a.k.a. the Prime Spiral and the Ulam Spiral) is constructed as follows: Consider a rectangular Grid. We start with the central point and arrange the positive integers in a spiral fashion (anticlockwise). The prime numbers are then marked. There is a tendency for the prime numbers to occur on diagonal lines, however Far out into the spiral one goes. This software is for exploring the Prime Number Spiral. It also (a) allows coloring of the prime numbers in various ways, (b) displays a random arrangement to compare with the Primes and (c) shows patterns formed by square and triangular numbers on the spiral.
