We show that, in the MIU formal system introduced by Hofstadter every word mx where x is a sequence of u's and i's having a number of i's which is not a multiple of 3, is a theorem. We give an algorithm that outputs a standard proof of every such word.

Keywords: Formal Systems, Complexity of proofs.
