Greetings,(adsbygoogle = window.adsbygoogle || []).push({});

I am using LyX. When I type

\@addtoreset{thm}{section},

in the preamble, the theorem numbering is reset at each section, as desired. Similarly, when I type

\@addtoreset{thm}{subsection},

in the preamble, the theorem numbering is reset at each subsection, as desired. However, when I type

\@addtoreset{thm}{subsubsection},

in the preamble, the command is ignored entirely. Does anyone know how to get it working, i.e., how to get the theorem numbering reset at each subsubsection?

Thanks very much for any help that you can give.
