English: Assigning {1,3,4} to the "C" bin and {2,4} to the "R" bin corresponds to choosing a permutation of these letters that represents the string CRCCR. Here it is understood that ${\displaystyle \{1,3,4\}}$ ${\displaystyle =}$ ${\displaystyle \{4,3,1\}}$ ${\displaystyle =}$ ${\displaystyle \{3,4,1\}\ldots \,.}$ The integers 1-5 are the distinguishable objects, while the three "C"s are identical, as are the two "R"s.
