I did not knowingly post an affiliate link. Of the parts of the URL, which is it? http: //www.amazon.com/ Art-Computer-Programming-Combinatorial-Information /dp /0201038048/ And, I did not edit the link. Perhaps some admin removed the affiliate part. However, when I go to the page in my browser, it looks just like it does above. Perhaps I followed a link to Amazon earlier in my session and picked up someone's affiliate link.
