As seen in Example 6, an r-combination is simply an r-element subset of the set. It is interesting to notice that the three tiles from each of the above combinations can be arranged in 3! If we generalize the top end of the loops from \$10\$ to \$n\$, and the number of for loops from 4 to \$r\$, clearly, we'll be counting (the hard way) the number of \$r\$-combinations with repetition from an \$n\$ element set, i.e., \$n+r-1 \choose r\$. There are 3 men and 4 women in a company. Generalized Permutations Problems of this type tend to look something like: how many ways are there to permute n objects, where there are n 1 indistinguishable objects of type 1, n 2 objects of type 2, and so on.
