Abstract: Worldvolme theory of multiple M2-branes is one of the important objects in M-theory. Due to the non-commutativity of the degrees of freedom, the theory of multiple M2-branes also contains the information of M5-branes. In particular, there are heavy (D ~ N: number of M2-branes) operators in these theories which correspond to wrapped M5-branes under the AdS/CFT correspondence. In our work we found an exact large N expansion for a superconformal index of N M2-branes on different orbifold backgrounds, including the exact form of the effects of wrapped M5-branes. The results are consistent with the known exact forms of the superconformal indices of single and multiple M5-branes.
