I would like to draw in tikz
the following image:
I want to draw two triangles intersecting in the common triangles with the dashed box. However, I am finding it difficult though, could anyone help me please?
This is my code:
\begin{tikzcd}
a \arrow[r, "\lambda"] & b \arrow[r, "\mu"] \arrow[d,"\pi"] & c \arrow[r,"\ell"] \arrow[d,"\rho" ] & s \arrow[d,"\ell^\prime"] & \\
& d \arrow[r,"\sigma" ] \arrow[lu, squiggly] & e \arrow[r,"\mu^\prime"] \arrow[d, "\phi"] & x \arrow[r,"\theta"] \arrow[d,"\rho^\prime" ] & a[2] \arrow[d] \\
& & p \arrow[r,"\sigma^{\prime}"] \arrow[lu, squiggly] & y \arrow[r,"\theta^\prime"] \arrow[d] & b[2] \arrow[d] \\
& & & z \arrow[r,"\nu"] \arrow[lu, squiggly] & c[2] \arrow[d,"\ell{[2]}"] \\
& & & & s[2] \arrow[lu, squiggly]
\end{tikzcd}

I'm not quite sure whether the two triangles still should have their outline showing when they intersect or not, both options are shown in the picture.
Here I opted for the latter.
