How to code the syntax like fraction, but with more than 2 components? Fractions consist of numerator and denominator while I need more. In other words: how to code column-matrix with horizontal lines separations (and without any surrounding brackets).
P.S. All components should be of equal size not like in
{a \over {b \over {c \over d}}}
\over
which isn't really a LaTeX command. Something like {\scriptstyle\begin{array}{c}1\\2\\3\\4\\5\\6\end{array}}` should work in LaTeX/
