Relay questions can come in many forms. They typically start with let T = TNYWR (The Number You Will Receive). The idea is you can do a lot of work on solving the problem before you know what T is. Then when you receive T from a teammate, you can finish up your problem and get your answer.[br][br]Relays appear on [url]mathleague.org[/url] High School competitions and on ARML, [url]www.arml.com[/url], competitions.[br][br]This particular question is explained at [url]http://www.math-magic.com/misc/hexagonal.htm[/url]
