UConn Mathematics Graduate Student Ioanna Mavrea has again launched her Problem Competition. From her electronic-mail message to Mathematics faculty, staff and graduate students of September 3, 2002:

As always, I found some good problems over the summer and look forward to sharing them with you over the coming months. Suggestions of new ones are welcome.

Here's our first problem. As usual, there will be a reward for the first grad, or undergrad solution.
