This is a double question...
I would like to see a plot of primes such that there are concentric circles, with each circle representing a prime and having its number represented as evenly placed points around the circle. For example,
- r=2: two dots 180 degrees apart,
- r=3: three dots 120 degrees apart,
- r=4: five dots 72 degrees apart.
Surely someone has plotted this before but I can't google it and I don't recognise it if I've already seen it. Can someone link to one?
If I need to graph it myself, how can I express this on Wolframalpha or something?
Note: absolute math noob, if it's not obvious!
