An example follows of how to construct a character table for the finite group of permutations of three letters. Firstly establishing the number of irreducible representations (characters) of the group. Secondly establishing the degree of irreducible representations, the character table … Continue reading

The fundamental homomorphism theorem can be visualised as an instructive example is how a cyclic group is isomorphic to a quotient group structure and the corresponding homomorphism computes the remainders (mod n). Two numbers are congruent (mod n) if the … Continue reading
