# How many Anyons can be allowed in a state

For fermions, a state allows only one fermion to exist . For bosons, there can be infinite number of bosons in one state . But for anyons, how many can a state allow?How do we come to this conclusion?

• I heard that in parastatistics (one of several alternatives to the better known particle statistics models; Bose–Einstein statistics, Fermi–Dirac statistics) , specifically for parafermions of order p, there can be no more than p fermions in one state – Aleksey Druggist Jan 6 '20 at 9:53
• Try to look up Haldane's "Exclusion statistics". For example these notes by Murthy and Shankar, where the relation between exchange statistics and exclusion statistics is discussed. imsc.res.in/xmlui/bitstream/handle/123456789/334/… – Heidar Jan 7 '20 at 22:58
