Changing the numberings of nested lists in an Enumerate environment, in LaTeX

enumerate, latex

Solution

The purpose of the `{enumerate}` environment is to number things algorithmically. If you really want the numbers to appear as shown in your question, I can't identify what algorithm you want to be used. For the example you show, I think the easiest method is just to program the labels yourself instead of trying to program LaTeX to do it. I would just do it this way:

\begin{itemize}
\item[1.]  Item
   \begin{itemize}
    \item[2.  ] Item
    \item[3a. ] Item
    \item[3b. ] Item
    \item[4.  ] Item
   \end{itemize}
\item [5. ] Item
\end{itemize}

With LaTeX, the quickest path to a solution often involves brute force :-)

Problem

I want to produce the following in LaTeX: ``` 1. Item 2. Item 3a. Item 3b. Item 4. Item 5. Item ``` Basically I have already tried using nested `enumerate` environments, but I have a problem with implementing the different numberings. How can I do the above in LaTeX?
