Last week's challenge: This puzzle was created by Will Shortz for an event held recently at the Museum of Mathematics in New York City. Take the name of a classical Greek mathematician. The letters in his name can be rearranged to spell two numbers. What are they?

Winner: David Rosen of Syosset, N.Y.
Next week's challenge: The challenge comes from listener Carol Highland of Ephrata, Wash. Take the brand name of a popular grocery item, written normally in upper- and lower-case letters.
