Def: Let S= {a1, a2, ..., an} be a set, not all ai necessarily distinct. A word in S is an equivalence class of permutations of the elements in S, where two permutations are equivalent if they produce the same ordered list. a.) How many words on the set S = {F, LU,F,F} exist? b.) How many words on the set S = {R, 0,T,0,R} exist if T is in the middle?
