F = GF(2)
R.<x> = PolynomialRing(F)
n = 7
g = x^3 + x + 1
C = CyclicCode(g, n)

This publication is a companion guide and pedagogical walkthrough for San Ling’s "Coding Theory". It clarifies core concepts, provides worked examples, and offers solution strategies for typical exercises. The aim is to make the subject more accessible while preserving mathematical rigor. This instantly tells you if your manual calculation
