I have the following matrix:
\documentclass{article}
\usepackage{amsmath}
\begin{document}
$\begin{bmatrix}
\begin{vmatrix}
168 & 368 \\
368 & 1026
\end{vmatrix} & \begin{vmatrix}
26 & 368\\
70 & 1026
\end{vmatrix} & \begin{vmatrix}
26 & 168\\
70 & 368
\end{vmatrix}\\
\begin{vmatrix}
26 & 70\\
368 & 1026
\end{vmatrix} & \begin{vmatrix}
5 & 70\\
70 & 1026
\end{vmatrix} & \begin{vmatrix}
5 & 26\\
70 & 368
\end{vmatrix}\\
\begin{vmatrix}
26 & 70\\
168 & 368
\end{vmatrix} & \begin{vmatrix}
5 & 70\\
26 & 368
\end{vmatrix} & \begin{vmatrix}
5 & 26\\
26 & 168
\end{vmatrix}
\end{bmatrix} =
\begin{bmatrix}
36944 & -916 & -2192 \\
\end{bmatrix}
$
\end{document}
Each row contains a 2x2 determinant. The problem is that the vertical lines of the neighboring determinants are touching, creating the impression that this is a 3x1 matrix with three 6x2 determinants. I have experimented a little with adding [3pt]
after the delimiting \\, but had no success. Any help will be appreciated!
By the way, I am calling LaTeX from a Markdown document, which means using extra/alternative packages is highly undesirable (albeit possible after a manual intervention during text conversion). Thanks in advance!
