How many different ways of arranging 5 As, 6 Bs and 3 Cs that all Bs must be in groups of $2$, $4$ or $6$?
How many different ways of arranging 5 As, 6 Bs and 3 Cs that all Bs must be in groups of $2$, $4$ or $6$? For example, ABBCABBABBCAAC and BBBBAABBAAACCC. We learned how to arrange ABC without the restrictions but confused when arranging B as groups of $2$, $4$ or $6$.

Just view your problem as 5 $A$s, 3 $C$s, and 3 "Siamese-twin $B$s".
