Increasing nesting in sub headings with LaTeX

Question

The following is an example of what I currently have:

\setcounter{secnumdepth}{3}

\chapter{The Chapter}

\section{First Section}
\subsection{First sub Section}
\subsubsection{First sub sub Section}

which renders something like this:

Chapter 1
The Chapter

1.1 First Section
1.1.1 First Sub Section
1.1.1.1 First sub sub Section

---

Now unfortunately in LaTeX, I can only go down to a subsubsection (1.1.1.1) but I need to be able to go down further...for example, something like this 1.1.2.1.3. Are there any commands that will allow me to do this?

Answer 1

Try this:

\setcounter{secnumdepth}{5}

Then you can get two more levels by using \paragraph and \subparagraph. For even more levels you need to extend standard LaTeX's sectioning mechanism. It's not actually difficult, just tedious to do.

Answer 2

even further, with the book class you have:

part
chapter
section
subsection
subsubsection
paragraph
subparagraph

and if that's not good, I whipped up this .sty file a little while ago:
