+# mathfam256
+
+LaTeX2e kernel 2015/01/01 increased the upper limit of math alphabets from 16
+to 256 for XeTeX/LuaTeX. Also, pLaTeX2e kernel 2016/11/29 introduced the similar
+change for e-pTeX/e-upTeX. However, the upper limit for math symbol families
+remains unchanged, so only 16 symbol fonts are available.
+
+This package increases the upper limit of math symbols from 16 (LaTeX2e default)
+to 256, using `\omath...` primitives. These primitives are originally introduced
+in Omega, and are currently available in the followings:
+
+- e-pTeX/e-upTeX (Japanese TeX engine)
+- Aleph (successor of Omega)
+
+## Supported formats
+
+The package mathfam256.sty works on the following formats:
+
+- pLaTeX (run on e-pTeX)
+- upLaTeX (run on e-upTeX)
+- Lamed (run on Aleph)
+
+All of these are enabled in TeX Live by default.

+
+In classic \TeX\ and \eTeX, the upper limit of math groups (\verb+\fam+)
+is limited to 16. However, these days some \TeX\ variants support
+math groups up to 256.
+
+In light of this situation, the \LaTeXe\ kernel 2015/01/01 increased
+the upper limit of math alphabets to 256 for
+Xe\TeX\ and Lua\TeX\ (Unicode \TeX\ variants).
+Also, the \pLaTeXe/\upLaTeXe\ kernel 2016/11/29 introduced the similar
+change for \epTeX/\eupTeX\ (``FAM256'' patch based on \OMEGA\ is applied).
+
+However, the ``native'' kernel support is limited:
+\begin{itemize}
+\item Lamed (\LaTeX\ on Aleph) is not supported at all.
+\item The upper limit for math symbol families is still limited to 16.
+\end{itemize}
+
+The package \textsf{mathfam256} is an attempt to resolve this situation;
+increases the upper limit of math symbols from 16 (\LaTeXe\ default)
+to 256, using \verb+\omath...+ primitives.
+
+The package is maintained on GitHub:

+\end{quote}
+
+\section*{Requirements}
+
+The \verb+\omath...+ primitives are originally introduced in
+\OMEGA\ (Omega), and are currently available in the followings.
+Without one of these, the package causes an error.
+\begin{itemize}
+\item \pLaTeX/\upLaTeX, run on \epTeX/\eupTeX\ (Japanese TeX engine)
+\item Lamed, run on Aleph (successor of \OMEGA)
+\end{itemize}
+
+\section*{Usage}
+
+Load it in the preamble; it is recommended to load it as fast as
+possible.

+
+オリジナルの\TeX や“素”の\eTeX では、数式ファミリ(\verb+\fam+)の
+上限が16個に制限されていました。しかし、最近の新しい\TeX エンジンの中には、
+256個までの数式ファミリをサポートするものが現れています。
+
+この状況を鑑み、\LaTeXe カーネル（2015/01/01以降）では、
+Unicode対応のXe\TeX とLua\LaTeX について、数式ファミリ（正確には
+\verb+\DeclareMathAlphebet+で使われる数式アルファベット）の上限を256に
+増やしています。同様に、\pLaTeXe/\upLaTeXe カーネル（2016/11/29以降）も、
+\OMEGA ベースのいわゆる「FAM256パッチ」が適用された\epTeX/\eupTeX について、
+数式ファミリの上限を256に増やしています。これらにより
+\begin{verbatim}
+  ! LaTeX Error: Too many math alphabets used in version normal.
+\end{verbatim}
+というエラーが発生しにくくなっています。
+
+しかし、この“ネイティブな”カーネルのサポートには限界があります：
+\begin{itemize}
+\item Lamed (\LaTeX\ on Aleph)は全く考慮されていない。
+\item 数式シンボルフォントの上限は依然として16のままである（安全のため）。
+\end{itemize}
+
+この\textsf{mathfam256}パッケージは、この状況を改善する試みです。
+すなわち、\OMEGA 由来の\verb+\omath...+プリミティブを用いて、
+数式シンボルフォントの上限を256に増やします。
+
+\section*{動作条件}
+
+もともと\OMEGA\ (Omega)に導入された\verb+\omath...+プリミティブが
+必要です。これが実装されているのは、以下のフォーマット（エンジン）です。
+これ以外でパッケージが使われて場合はエラー終了します。
+\begin{itemize}
+\item \pLaTeX/\upLaTeX （\epTeX/\eupTeX 上で動作）
+\item Lamed（\OMEGA の後継であるAleph上で動作）
+\end{itemize}
+
+\section*{使い方}
+
+プリアンブルで読み込みます。なるべく早めに読み込むことをお勧めします。

+\section*{謝辞}
+
+本パッケージは\cite{yamamoto}〜\cite{yamamoto3}を元に、
+新しい\LaTeX に対応させることで作られました。
