Handbook guide to quartic galois groups and resolvent cubics with core definitions, structural results, reasoning methods and verification checks.
Determining Galois groups in degree five, where solvability by radicals first fails and the resolvent degrees grow.
Degrees six and seven, where the number of candidate groups and the resolvent degrees make careful strategy essential.
What computing a Galois group means, why the splitting field cannot be constructed, and the transitive group classification that makes the problem finite.
Constructing resolvent polynomials whose factorisation distinguishes candidate Galois groups, and the practical issues in using them.
