# Remove indent in subsubsection heading

I wish to remove the indent created by Latex at the start of the sub-sub-section heading
'Confidence Set', consider the below MWE

\subsubsection{\textbf{\underline{Confidence Set}}}
We denote this set as $C^*$.\\
Say, the support of r.v. $X$ has n indices 1,2,\ldots,n. Then, to find $C^*$, we\\
(i) First sort the empirical p.m.f. in descending order and obtain the sorted indices as $q_1,q_2,\ldots,q_n$.\\
$$\sum_{i = 1}^{k}p(x_i) > 1 - \epsilon$$
Thus, the confidence interval is the minimal such interval whose cumulative probability is greater than (1 - $\epsilon$) where $\epsilon$ is a small number, and is modelled as a Hyper-Parameter.\\
\end{document}


The output produced is:

I wish to remove the indent at the start of line 5.

re-def \thesubsubsectiondis

Place this command before begin{document}

\def\thesubsubsectiondis{\unskip\arabic{subsubsection})}


Hope this helps

• Thank you, this removes the indent but it also removes the closing parenthesis after 1 i.e. 1) becomes 1 . Any way we can keep the ) or add a . instead of the ) ? – ijuneja Dec 10 '19 at 6:45
• i update my answer with the closing parenthesis. You can add ) or . or what ever you like after \unskip\arabic{subsubsection} – Samjith Dec 10 '19 at 6:54
