[Tex/LaTex] Extending the document structure hierarchy for a report

sectioning

For a 11 pt. report document class which I am using for my thesis, I can only get the following heading levels on a per chapter basis:

\chapter

\section

\subsection

\subsubsection

I am not including the paragraph sections above, as they do not pertain to headings.

My question is: is there a way to extend the above limited hierarchy to include more heading levels? Alternatively, is there a package which provides such an extension?

For example in the following MWE:

\documentclass[11pt]{report}
\begin{document}
\tableofcontents
\part{This is a part}
\chapter{This is a chapter}
\section{This is a section}
\subsection{This is a subsection}
\subsubsection{This is a subsubsection}
\paragraph{This is a paragraph}
\subparagraph{This is a subparagraph}
\end{document}

There is no numbering generated for the paragraph or the subparagraph….so these would not be captured in TOC. I need to create a numbered hierarchy with more depth than that allowed by above. My actual need is to have another level above the \section{} to form a generic heading for the discussion that follows in the section and the subsections. Is there a way to do this in such a way that it is sequentially numbered automatically, and captured in TOC as well?

TIA

The next heading levels are \paragraph and \subparagraph they do pertain to headings they are defined using \@startsection almost exactly the same as \section, but at levels 4 and 5.

The source of these commands in report.cls is below:

\newcommand\section{\@startsection {section}{1}{\z@}%
                                   {-3.5ex \@plus -1ex \@minus -.2ex}%
                                   {2.3ex \@plus.2ex}%
                                   {\normalfont\Large\bfseries}}
\newcommand\subsection{\@startsection{subsection}{2}{\z@}%
                                     {-3.25ex\@plus -1ex \@minus -.2ex}%
                                     {1.5ex \@plus .2ex}%
                                     {\normalfont\large\bfseries}}
\newcommand\subsubsection{\@startsection{subsubsection}{3}{\z@}%
                                     {-3.25ex\@plus -1ex \@minus -.2ex}%
                                     {1.5ex \@plus .2ex}%
                                     {\normalfont\normalsize\bfseries}}
\newcommand\paragraph{\@startsection{paragraph}{4}{\z@}%
                                    {3.25ex \@plus1ex \@minus.2ex}%
                                    {-1em}%
                                    {\normalfont\normalsize\bfseries}}
\newcommand\subparagraph{\@startsection{subparagraph}{5}{\parindent}%
                                       {3.25ex \@plus1ex \@minus .2ex}%
                                       {-1em}%
                                      {\normalfont\normalsize\bfseries}}

\documentclass[11pt]{report}
\setcounter{secnumdepth}{5}
\setcounter{tocdepth}{5}
\begin{document}
\tableofcontents
\part{This is a part}
\chapter{This is a chapter}
\section{This is a section}
\subsection{This is a subsection}
\subsubsection{This is a subsubsection}
\paragraph{This is a paragraph}
\subparagraph{This is a subparagraph}
\end{document}

[Tex/LaTex] scrreprt – add levels below \subparagraph

Quoting the manual from the titlesec package:

With the help of classes you may insert, say, a new subchapter level between chapter and section, or creating a scheme of your own.

(at subsection 3.9 in the titlesec.pdf).

At appendix 9.2, it shows exactly how the already existing sections and the like are defined; don't copy the already existing parts to your file, but use them as inspiration for defining new ones (amount of indentation, style, etc). My advice is to look at all the appendices and subsection 3.9.

[Tex/LaTex] \subsubsection in a report style document

The default depth of the ToC in report is 2 (contained within the counter tocdepth). This means that sectional units up to and including this level will be included in the ToC. Here are the levels based on the standard document classes:

\part = -1
\chapter = 0
\section = 1
\subsection = 2
\subsubsection = 3
\paragraph = 4
\subparagraph = 5

If you wish for your subsubsections to be included, add

\setcounter{tocdepth}{3}% Include \subsubsection in ToC

to your document preamble. Here's a MWE showing the resulting output:

enter image description here

\documentclass{report}
\setcounter{tocdepth}{3}% Include \subsubsection in ToC
\begin{document}
\tableofcontents
\chapter{A chapter}
\section{A section}
\subsection{A subsection}
\subsubsection{A subsubsection}
\end{document}

Note that \subsubsections are not numbered by default. If you wish to have them numbered (in the ToC as well), then you also need to include

\setcounter{secnumdepth}{3}% Number \subsubsection

in the preamble also. The default, just like tocdepth is 2. Here's an view with the update:
