Galois is not the founder of group theory.

The domestic literature (Popular science China) has said that Galois is the discovery and founder of group theory. This does not accord with historical facts.

In fact, the work of Galois is to use permutation group tools to solve the existence of a radical solution to the polynomial conditions.

The study ofgroups originally grew out of a understanding of permutation groups (permutation group). Permutationshad themselves been intensively studied by Lagrange in 1770 in he work on thealgebraic solutions of Polynomia L equations.

The study shows that any finite group is isomorphic to a permutation group. The research project was later developed.

This subjectflourished and by the mid 19th century a well-developed theory of permutationgroups existed, codified by Camil Le Jordan in He book Traitédes Substitutionset deséquations algébriques of 1870. Jordan's book is, in turn, based on Thepapers that were left Byévariste Galois in 1832.
