β¦ Synopsis
The exclusion statistics parameter of composite fermions is determined as an odd number ( = 3, 5, ...). The statistics of composite fermion excitations at = n=(2pn + 1) is rederived as CF qe = 1 + 2p=(2pn + 1), CF qh = 1 -2p=(2pn + 1). The duality 1=( qe(n; 2p)) = qh (n + 1; 2p) is found. The distribution function for = 3 is obtained.
