I am writing my thesis with overleaf. I have used a book document class and I am proceeding in the enumeration of the chapters, sections and subsections. It looks fine from section to subsection where I want numbers both in the main file that in the table of contents.

The problem is that for subsubsection I would like to have a bullet (or any kind of pointing symbol) instead of numbers both in the main file and in the table of contents (in both cases indented, even if I think that in the toc it would be automatically indented). I do not know I to fix the problem. I tried with the * to delete the number, but then I do not know how to add the bullet and anyway in the text I would have still the number. Is there someone who could help me? Thanks a lot for your help. The basic code could be this one

\chapter{} \section{} \section{} \subsection{} \subsubsection{}

The last part, that is the subsubsection I would like to have it without numbers both in the main file and in the toc and replacing numbers with bullet or any pointing symbol.

• Welcome to TeX SX! Could you post a small complete code, that we can play with? – Bernard Nov 14 '18 at 20:18

\documentclass{book}
\setcounter{secnumdepth}{3} % number subsubsections
\setcounter{tocdepth}{3} % put subsubsections in ToC
\renewcommand{\thesubsubsection}{\ensuremath{\clubsuit}} % no number, fancy glyph
\begin{document}
\tableofcontents}
\chapter{Chapter}
\section{Section}
\subsection{Subsection}
\subsubsection{Subsubsection}
\end{document}
