For some reason, the text I had cut-and-pasted from doc-1.8.pdf did not 
went successfully through the mailing list software (parts were 
removed). Here the original text, pasted from doc-1.8.tex:

\OMEGA, on the other hand, allows 256 ($2^8$)
font families, each font of 65~536 ($2^{16}$) characters.
So, in addition to the \TeX\ math font primitives, which continue to 
work,
there are 16-bit versions:
[...]
\item \verb|\omathchar| $\bits{27}$:\\
Generates a math character with 27-bit math code;
[...]
where
[...]
\item $\bits{27}$ refers to value \texttt{0x8000000} or a triple
\begin{itemize}
\item 3 bits for math category,
\item 8 bits for font family,
\item 16 bits for character in font,
\end{itemize}
called a \emph{math code};
