Category:Pigeonhole principle
The pigeonhole principle states that if <m>n</m> objects (pigeons) are to be placed in fewer than <m>n</m> sets (holes), then at least one set must contain more than one object. Puzzles in this category all make use of the pigeonhole principle, although rarely explicitly.
