Hi everyone,

Several students did optional computer projects this year. The first is a finite field calculator, which will multiply elements of a finite field. These are respresented as polynomials in x, a primitive element. To find out what polynomial is being used to generate the finite field, try multiply the appropriate power of x.

The second is a permutation calculator. It will conjugate, multiply and find inverses for permutations on as many as 9 elements.

Enjoy and happy holidays everyone!
