Indivisible is a program for working with prime numbers. Its default behaviour will attempt to find the \fInth\fR prime. Indivisible is a program for working with prime numbers. It can either generate
primes up to a limit \fIn\fR or test to see if \fIn\fR is a prime. It makes use
of a segmented sieve of Eratosthenes.
