Connes discovered that changing the state does not change the image of the modular automorphism in the outer automorphism group of " M ".

For example, for the alternating group, } }, the outer automorphism group is usually the group of order 2, with exceptions noted below.

The alternating groups usually have an outer automorphism group of order 2, but the alternating group on 6 points has an Schur multiplier of order 6.

Diagram automorphisms correspond to outer automorphisms of the Lie algebra, meaning that the outer automorphism group Out = Aut / Inn equals the group of diagram automorphisms.

This exceptional outer automorphism is realized inside of the Mathieu group M 12 and similarly, M 12 acts on a set of 12 elements in 2 different ways.

We have seen above that there is a canonical homomorphism ? from the group of reals to the outer automorphism group of a von Neumann algebra, given by modular automorphisms.

This corresponds to the outer automorphism that's unique to S 6 ( among symmetric groups ) .-- talk ) 14 : 15, 4 May 2010 ( UTC)
