Fano statistical tensor parameters is a well known aspect for expression the density matrix of spin-j states. Enumeration SU(2) invariants for the most general symmetric states were constructed with making use of Multiaxial representation of spin-j density matrix into j (2j + 1) axes and 2j real scalars (Sirsi and Adiga J. Russ. Laser Res. 32, 495, 2011). In this paper we will enumerate a complete set of invariants for Bell state and three qubit GHZ state using Multiaxial representation of the density matrix.
