Umm... yes, you should actually.
Those patterns of semicircles aren't random, of course. They correspond directly to the degree of compositeness of the chosen modulus. Compare for n = 60,61,62, for example.
The higher the totient value for n, the more circles you see, basically.
- marshray 14y agoRight, so I can look at the diagram and see that 59 and 61 are prime while 60 has many divisors. I can kinda see that the density of primes decreases gradually. But I can't see a broader pattern beyond that. Now here I can see some patterns! https://en.wikipedia.org/wiki/Ulam_spiral https://en.wikipedia.org/wiki/Ulam_spiral
