On the density of Euler’s Phi function of the sets of numbers in form of p+/-n and their relation to
 
Hey everyone,
I found an interesting property of the sets of the numbers in form of p+/-n (all the primes being shifted forward or backward by the given n)
It occurs the average density of Euler’s Phi function of the numbers within such sets is directly linked with the Artin’s constant and depends only on the unique divisors of n.
More details you can find [URL="https://numbersplane.blogspot.com/2022/03/on-density-of-eulers-phi-function-of.html"]here[/URL].
I couldn’t find anything anywhere mentioned about this relationship, but maybe someone of you has seen something?
