Abstract
Having pursued some of the consequences of Fermat’s observation, I now invite you to delve back into the mysteries of the structure of the integers. In these next two chapters we will be pulling out a few more jewels that we can apply to our twin problems of factorization and primality testing.
“When you have to study a large number, you should begin by finding some of its quadratic residues.”
