Let there be planes \( \alpha \), \( \beta \), \( \gamma \) and \( \delta \) defined by their general equations:
\[ \begin{aligned}
&\alpha\colon \frac23x-4y+6z-\frac83=0; \\
&\beta\colon x-2y+3z-4=0; \\
&\gamma\colon 2x-12y+18z-4 =0; \\
&\delta\colon x-6y+9z-4 =0.
\end{aligned} \]
Out of the following statements, select the one that is not true.
\( \alpha \parallel\delta\text{, }\alpha\neq\delta \)
Planes \( \beta \) and \( \delta \) are intersecting.
\( \gamma\parallel\delta\text{, }\gamma\neq\delta \)
Planes \( \alpha \) and \( \beta \) are intersecting.
\( \alpha = \delta \)
