To do so, the agency has identified twenty-three mathematical challenges, listed below, which were announced at DARPA Tech 2007.

Is symmetry informative? The answer is both yes and no. We examine what information and symmetry are and how they are related. Our approach is primarily mathematical, not because mathematics provides the final word, but because it provides an insightful and relatively precise starting point.

In this respect the studies of information and symmetry can both be regarded as a Quest for the identity transformation.
