Automorphisms of order 3 in $C_2$ X $C_2$ X $C_2$

Question

I am trying to find out the number of automorphisms there are in $C_2$ $\times$ $C_2$ $\times$ $C_2$ $\cong <x,y,z|x^2=y^2=z^2=1>$. I only can come up with the one which moves $x \rightarrow y \rightarrow z \rightarrow x$ and the inverse. However, the problem is that I watched a proyect which says that there are 54 elements of order 3 in the Aut$(C_2 \times C_2 \times C_2)$. I do not know whether I am wrong or the proyect.
