phillip1882 Posted September 16, 2019 Report Posted September 16, 2019 (edited) Let E be an even number.between 1 and 2*E there will be a number such that it is prime, and it plus E is prime. lets call this number P.after that, between P and 2*P+E, there will be another number such that it and it plus E is prime.repeat indefinitely. for example, let E = 8.3,11 the next between 3 and 145,13 the next between 5 and 1811,19 the next between 11 and 3023,31 the next between 23 and 5429,37 the next between 29 and 66 for E = 143, 175, 1917, 3123, 3729, 43 Edited September 16, 2019 by phillip1882 Quote
LaurieAG Posted September 17, 2019 Report Posted September 17, 2019 Hi Phillip1882, that looks interesting. You may have to change 'between' as 6 looks like it only works on the first cycle with 1, 7. 4 and 2 also require 1 to be in their range to get primes but I haven't looked any further. Where's Turtle when you need him. ;) Quote
