Produced with


which uses the amsmath package.

It works fine most of the time but I prefer to avoid manually raising boxes when I can, so I keep wondering if there is a smarter way to reach this kind of horizontal and vertical alignment. (Note that this command is often deeply nested in more complex constructs.)

    Can you please show a use case of your macro? – egreg Jul 16 '13 at 15:22
  • @egreg: I added the code I used to generate the example. – François G. Dorais Jul 16 '13 at 15:52

You can exploit \vcenter:


\makeatletter % Hendrik Vogt (https://tex.stackexchange.com/a/4827)
\def\vcdots{\vbox{\baselineskip4\p@ \lineskiplimit\z@


[\Gamma] \\
\lrscript{\vcdots}{\pi}{\existsfree} \\

The macro \vcdots for better vertical dots is by Hendrik Vogt

  • Neat! Is there a \vbottom too? – François G. Dorais Jul 16 '13 at 16:03
  • @FrançoisG.Dorais It's \vbox. – egreg Jul 16 '13 at 16:05
