Decomposing a finite-dimensional commutative algebra over a finite field into its simple components, generalising polynomial factorisation.
Decomposing any prime, including those dividing the index, by splitting the algebra of the order modulo that prime.
Boolean rings, the mutual translation with Boolean algebras, term equivalence as the precise relationship, and why the ring picture makes ideals and the prime spectrum available.
