The Galois group of the splitting field for the degree-six polynomial over the rationals is isomorphic to the alternating group, resolving full symmetry by hand calculation.
Manual derivation establishes that the six roots of the polynomial correspond to tetrahedral edges, while four auxiliary roots align directly with the four geometric faces.
Geometric alignment allows complete explicit identification of all eight proper intermediate fields, providing a concrete classroom model for advanced Galois extension theory.
