Preferably using the enumitem package, how can I create a list of this form?

(1), (2) First item
(3) Second item
(4) Third item
  • Are you going to reference the items as well?

  • Yes. I would like to be able to reference the numbers individually.

  • This sort of breaks the format of any normal list. What list features do you want to retain: hanging indentation, multiple paragraphs, nesting with other list environment, page breaking? Aug 29 '17 at 21:03
  • @JohnKormylo Indentation can be determined by the other list items. Multiple paragraphs and page breaking are essential. Nesting with other list environment is not currently needed but what would be the issue here?

You could set the first item (and accompanying horizontal alignment) manually:

enter image description here





\begin{enumerate}[label={(\arabic*)}, start=3, leftmargin=*]
  \item[] \hspace*{\dimexpr-\labelindent-\labelwidth-\labelsep+\itemindent}%
    (1), (2) \hspace{\itemindent}First item
  \item \label{second} Second item
  \item Third item
  \item etc.

See items~\ref{first-a} and~\ref{first-b}, or~\ref{second}.


We also set the reference manually via \setref{<stuff>}, after which one can use \label in the usual way. If hyperref is loaded, consider adding \phantomsection to appropriately mark the hyperlink to jump to.

  • Are you interested in referencing (1) or (2)?

  • Both if possible. If not then (1) is fine.

  • Very nice! hyperref is indeed loaded, thanks for the hint.
