I am writing a thesis using \documentclass[11pt,a4paper]{report}. However, \subsubsection is not getting numbered. So on searching in TeX I got an answer to insert \setcounter{secnumdepth}{3}.

Please tell me where to insert \setcounter{secnumdepth}{3}.

Commands like this belong into the preamble, i.e. between \documentclass and \begin{document}. If you want your \subsubsections also to be appear in the table of contents you should add \setcounter{tocdepth}{3} as well. Please see How to show subsections and subsubsections in TOC? for more information about this, including a list of sectioning levels and their numbers.




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