The following code compiles fine:

\documentclass{article}
\usepackage{amsmath}
\begin{document}
\begin{equation}
\begin{split}
    1 & 2 \\
    4 & 5 
\end{split}
\end{equation}
\end{document}

While replacing the contents of the split with

1 & 2 & 3\\
4 & 5 & 6

results in Extra alignment tab has been changed to \cr. It looks like split supports only two "columns", but I can't find any mention of that, neither in the manual nor anywhere else.

Yes, and it is mentioned in the documentation, page 4:

  • Thanks. It seems I was looking at outdated documentation: ams.org/arc/tex/amsmath/amsldoc.pdf
