  • It is true that one of the fundamental concepts in mathematics is the idea of a one-to-one correspondence between elements of two distinct sets.

  • The pigeonhole principle states that if n pigeons are put into m pigeonholes, and if n > m, then at least one pigeonhole must contain more than one pigeon. Another way of stating this would be that m holes can hold at most m objects with one object to a hole; adding another object will force you to reuse one of the holes. The first statement of the principle is believed to have been made by Dirichlet in 1834 under the name Schubfachprinzip ("drawer principle").
