Though the main purpose of this section is to provide background necessary for the next chapter on groups, permutation have been studied much longer than groups have. One of their original motivations, in the 1700's by French mathematicians such as Lagrange and Galois, were as a tool to understand how the roots of a polynomials depended on the coefficients.
