我想在一个圆圈周围放置 p 个间距均匀的节点。

我想使用文档类[报告]绘制下面的图片。

在此处输入图片描述

编辑：我到目前为止所做的

\documentclass[a4paper,leqno,11pt]{amsart}

\usepackage{amsfonts,amssymb,verbatim,amsmath,amsthm,latexsym,textcomp,amscd}
\usepackage{latexsym,amsfonts,amssymb,epsfig,verbatim}
\usepackage{amsmath,amsthm,amssymb,latexsym,graphics,textcomp}
%\usepackage[all,2cell,dvips]{xy}
\usepackage{graphicx}
\usepackage{color}
\usepackage{url}
\usepackage{tikz}

\begin{document}
\begin{tikzpicture}
\def \n {5}
\def \radius {1.5cm}
\def \margin {3}
\foreach \s in {1,...,\n} {%
   \node [anchor=center] at ({360/\n * (\s-1)}:\radius+ 1){$g^{\s}$};
   \filldraw[black] ({360/\n * (\s-1)}:\radius) circle (1pt) ;
   \node [anchor=center] at ({360/\n * (\s-1)}:\radius+0.3cm ){$g^{\s}$};
   \draw[>=latex] ({360/\n * (\s-1)+ \margin}:\radius)
      arc({360/\n * (\s-1)+\margin}:{360/\n * (\s)-\margin}:\radius);
}
\end{tikzpicture}
\end{document}

这可以在一个 中完成\draw。

\documentclass{article}
\usepackage{tikz}

\begin{document}
    \begin{tikzpicture}
        \def \n {20}
        \def \radius {3}
        \draw circle(\radius)
              foreach\s in{1,...,\n}{
                  (-360/\n*\s:-\radius)circle(.4pt)circle(.8pt)circle(1.2pt)
                  node[anchor=-360/\n*\s]{$g^{\s}\ifnum\s=\n\relax=e\fi$}
              };
    \end{tikzpicture}
\end{document}

省略版本

\begin{tikzpicture}
    \def \n {20}
    \def \radius {3}
    \draw circle(\radius)(0:-\radius)circle(.4pt)circle(.8pt)circle(1.2pt)
          foreach\s in{0,...,7}{
              ({-360/\n*(\s-1)}:-\radius)circle(.4pt)circle(.8pt)circle(1.2pt)
              node[anchor={-360/\n*(\s-1)}]{$\ifcase\s\relax g^{p-1}=g^{-1}\or g^p=e\else g^{\pgfmathparse{int(\s-1)}\pgfmathresult}\fi$}
          }
          foreach\s in{9,...,\n}{
              ({-360/\n*(\s-2)}:-\radius)
              node[anchor={-360/\n*(\s-2)}]{$\cdot$}
          };
\end{tikzpicture}
