Output of my quantum circuit to create 3-qubit GHZ-like state does not make sense mathematically

I want to create the GHZ-like state, $|\Psi\rangle = \frac{1}{\sqrt{2}} \left(|011\rangle - |100 \rangle \right)$. I build my circuit in the following way. apply the x gate to the first and third ...

Difference between a star graph state and GHZ graph state

I saw in a class that star state and GHZ state are local-Clifford equivalent (Hadamard on n-1 qubits for a n star state). But then, when I wanted to draw a GHZ state and check on the litterature ...
