A men’s basketball league assigns every player a two-digit number for the back of his jersey. If the league uses only the digits 1–5, what is the maximum number of players that can join the league such that no player has a number with a repeated digit (e.g., 22), and no two players have the same number?

5 numbers so 5C1
then the number should be non repeating so 4C1
5C1*4C1 = 20
then the number should be non repeating so 4C1
5C1*4C1 = 20
