Abstract
Two-dimensional rational CFT are characterised by an integer , related to the number of zeroes of the Wronskian of the characters. For two-character RCFT's with there is a finite number of theories and most of these are classified. Recently it has been shown that for there are infinitely many admissible characters that could potentially describe CFT's. In this note we examine the case, whose central charges lie between 24 and 32, and propose a classification method based on cosets of meromorphic CFT's. We illustrate the method using theories on Kervaire lattices with complete root systems. In the process we construct the first known two-character RCFT's beyond .
