It is known that the Hilbert space dimensionality for quasiparticles in an SU(2)(k) Chern-Simons-Witten theory is given by a number of directed paths in certain Bratteli diagrams. We present an explicit formula for these numbers for arbitrary k. This is on the basis of a relation with Dyck paths and Chebyshev polynomials. Copyright (c) EPLA, 2009
