It is possible to make prime pairs (p,p+n) calculator for any n using two fanouts, delaying device and AND logic gate. Just delay one fanout by 120*n, take it as one input for AND gate and take second, non-delayed fanout as second input, then output shots glider iff number p and number p+n is prime

Thanks Andrew — I hadn’t seen that before and am quite impressed by it! Time for me to learn a bit more about rule tables so that I can understand it better.

Nathaniel, in case you haven’t seen this, download http://myweb.tiscali.co.uk/calcy/life/simulators.zip, install Primes.table and .colors in Golly’s rules folder and then load primer.rle. This is a 2-cell(!) pattern that emulates Dean’s primer Life pattern using a 10-state rule.
