It's a reflection :) look up colin Dodds geometric transformations that's how I learned it it's a fun song
3 and 11 are the only two because 33 only has four factors: 1,3,11,33.
1 - in some cases people say this is prime, but it is now widely considered to not be a prime number
3 - prime
11- prime
33 - not prime, divisible by 3 and 11
