Spectra of these theories can be decomposed into the irreducible representations of the Fischer-Griess Monster sporadic group. Interesting periodicities in the coefficients of extremal partition functions are observed and interpreted as a possible extension of Monster moonshine to c=24k holomorphic field theories.4 pages, to appear in the proceedings of the "IV International Symposium on Quantum Theory and Symmetries," 15-21 August 2005 at Varna Free University, BulgariaHigh Energy Physics - TheoryMathematical Physicstext
