Year of discovery
1991
Primer is a pattern that was constructed by Dean Hickerson on November 1, 1991 that produces a stream of lightweight spaceships representing prime numbers. N is prime if and only if a lightweight spaceship escapes to the left of the pentadecathlon at the bottom-left corner of the pattern at generation 120N+100.[1] [2] It was the first pattern created that computes prime numbers, though others have since been constructed using the same ideas (see glider gunless primer ).
It works by using gliders to emulate a prime number sieve . Lightweight spaceships that move westward are deleted by gliders that represent positive integers if the lightweight spaceship represents a multiple of that number.
