The existence of the number operators N(k) in a general quon algebra i
s proved and a general construction of N(k) is Presented. A new genera
l simple structure of N(k) is proved when \q(ij)\ < 1, for-all i, j is
-an-element-of S, General recurrent relations for the corresponding co
efficients are constructed and solved in special cases. These solution
s are discussed and a conjecture for a general solution is proposed. C
ases in which some or all \q(ij)\ = 1 are discussed.
