The numbers {0,...,p-1} with p prime, and addition and multiplication
given modulo p (ie

a plus b = (a+b) mod p
a times b = (ab) mod p


is an interesting mathematical object known as a finite field (or
Galois field) - 

Interesting examples of infinite fields are those quite familiar to
you: rational, real and complex numbers.

It might make sense for Torgny to work with a Galois field for some
large but unnamed prime :)
