我根据以下建议使用了以下代码在这里回答。
\documentclass{memoir}
\usepackage{amssymb}
\usepackage{tikz-cd}
\begin{document}
\begin{tikzcd}[column sep=1.2em]
0 \arrow[r] &
C_{3} \arrow[r,hook] &
\mathit{SL}_{3}(\mathbb{C}) \arrow[r,two heads] &
\mathit{PSL}_{3}(\mathbb{C}) \arrow[r] & 0
\\
0 \arrow[r] &
K \arrow[r,hook] &
\mathcal{V} \arrow[r,two heads] \arrow[u,hook] &
A_{6} \arrow[r] \arrow[u,hook] & 0
\end{tikzcd}
\end{document}
但这根本不起作用；交换图根本就不显示。更令人惊讶的是，我没有收到任何错误。但上面的代码对 来说运行得很好\documentclass{article}。我该怎么做才能让它在 上运行\documentclass{memoir}？
