  Several entanglement measures are used to define equivalence classes in the
set of hypergraph states of three qubits. Our classifications reveal that (i)
under local unitary transformations, hypergraph states of three qubits are
split into six classes and only one class of them is not equivalent to any
graph state; (ii) under stochastic local operations with classical
communication, for the single copy case hypergraph states of three qubits,
partitioned into five classes which can not be converted into a W state, are
equivalent to graph states; and (iii) when bipartite entanglement in three
qubits considered, hypergraph states of three qubits are split into five
classes and only one class of them has the same entangled graph as the W state.
