Hi, I've a cite for, Elementary Number Theory Underwood Dudley pp. 208 prob. 87 Unfortunately the only copy I can find is a 2nd ed. and the page numbers are off. If somebody who has this book could tell me what the chapter title is and a quote of the problem I'd appreciate it. I want to find out if it's still in the 2nd ed and if so what it's current identity is. Please respond directly, off list. Thanks. ____________________________________________________________________ The ultimate authority...resides in the people alone. James Madison The Armadillo Group ,::////;::-.
