This is an example for a Diagramm in Lyx, that works and that looks just fine.
\begin{CD}
A@>>>B\\
@a...@vvv\\
E@<<<D
\end{CD}
It produces a cycle from A over B over C to D.
What I want is a cycle from A over B to D and then again to A. I want a sort of
triangle.
Is this possible in Lyx?

iustifico
