### About

Each semester, the Challenge Problem Series offers a new set of mathematical puzzles, designed to stump and to entertain. Everyone, from near and far, is welcome to participate.

UConn students—undergraduate and graduate—who submit solutions by the indicated deadline that are deemed worthy are rewarded with chocolate (or, on occasion, something else if there is sensitivity to chocolate).

### Contact

The Challenge Problem Series is written and maintained by Professor Stuart Sidney and Professor Liang Xiao.
