> GF5 is the 3rd smallest finite field (GF2 and GF3 are smaller) There is also a field of 4 elements, since 4 is a power of a prime.

- dragontamer 5y agoFair. I guess I was implicitly staying away from extension fields because people's attention span will start drifing away the minute I start to attempt to explain how to perform modulo polynomial arithmetic over irreducible polynomials. Prime fields (GF2, GF3, GF5...) are just easier to explain than extension fields (GF (2^2), GF(3^2), GF(5^2)... GF(2^8)...)
