%N A129618 A method of using three consecutive coprimes to generate numbers either
one away from a prime or splitting two twin primes. The sequence
lists the first of a group of three coprimes.
%C A129618 In 50 trials of trios of consecutive coprimes, nine failed to be within
one of a prime; four split twin primes; and 37 were within one of
a prime. The results were 37 + 2x4 = 45 prime neighbors from 50 trials.
Does this sequence continue to produce primes with a probability
greater than mere chance?
%F A129618 The first group is 1,2,3; the 2nd is 2,3,5; the 3rd is 4,5,7 and so forth
as the first number increases by one. Place a group of three coprimes
a,b and c into a^2 + b^2 + c to see how close the sum comes to a
prime.
%e A129618 Take 12,13,17 to yield 12^2 + 13^2 + 17 = 144+169+17=330 which
%e A129618 is one away from the prime 331.
