数式famの制限についてちょっと遊んでみました(時期的には古い話題になるかも しれませんが)．TeXフォーラムの方で関連する質疑応答がなされているのですが， 直接の回答にはならないと思うのでこちらに貼ってみます．使用している TeXシステムは，2008年2月頃の W32TeX のフルインストールです． 最初は lambda でやっていたのですが，class7の処理が思い通りに行かず， luatex でやってみたらOKでした．luatex では plain TeX しか用意されて いないので，LaTeX の format を作り(素直にやったらハイフネーションパターン の読み込みではねられるので，英語だけにしたらできた)，下の文書ソースを 処理したところ，16個超の数式フォントが使用できました． ソースの \mbfl{L\ fam=\the\fam\ } のところが，標準の TeX の限界です． 最後に数式fam255番の luatex の限界をつけてみました．では，文書ソース です． 注意．luatex で LaTeX の format を作成して実行してください． 標準の latex or platex ではエラーになります． %%%% test.tex %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \documentclass{article} \makeatletter \def\document@select@group#1#2#3#4{% \ifx\math@bgroup\bgroup\else\relax\expandafter\@firstofone\fi {% \ifmmode % \ifnum\csname c@mv@\math@version\endcsname<\sixt@@n% 16個ではなく \ifnum\csname c@mv@\math@version\endcsname<256% 256個にする \begingroup \escapechar\m@ne \getanddefine@fonts{\csname c@mv@\math@version\endcsname}#3% \globaldefs\@ne \math@fonts \endgroup \expandafter\extract@alph@from@version \csname mv@\math@version\expandafter\endcsname \expandafter{\number\csname c@mv@\math@version\endcsname}% #1% \global\advance\csname c@mv@\math@version\endcsname\@ne \else \let#1\relax \@latex@error{Too many math alphabets used in version \math@version}% \@eha \fi \else \expandafter\non@alpherr\fi #1{#4}% }% } \makeatother \DeclareMathAlphabet{\mbfa}{OT1}{cmr}{m}{n} \DeclareMathAlphabet{\mbfb}{OT1}{cmr}{bx}{n} \DeclareMathAlphabet{\mbfc}{OT1}{cmr}{bx}{n} \DeclareMathAlphabet{\mbfd}{OT1}{cmr}{bx}{n} \DeclareMathAlphabet{\mbfe}{OT1}{cmr}{bx}{n} \DeclareMathAlphabet{\mbff}{OT1}{cmr}{bx}{n} \DeclareMathAlphabet{\mbfg}{OT1}{cmr}{bx}{n} \DeclareMathAlphabet{\mbfh}{OT1}{cmr}{bx}{n} \DeclareMathAlphabet{\mbfi}{OT1}{cmr}{bx}{n} \DeclareMathAlphabet{\mbfj}{OT1}{cmr}{bx}{n} \DeclareMathAlphabet{\mbfk}{OT1}{cmr}{bx}{n} \DeclareMathAlphabet{\mbfl}{OT1}{cmr}{bx}{n}% ここで15番 \DeclareMathAlphabet{\mbfm}{OT1}{cmss}{m}{n} \DeclareMathAlphabet{\mbfn}{OT1}{cmss}{m}{n} \DeclareMathAlphabet{\mbfo}{OT1}{cmss}{m}{n} \DeclareMathAlphabet{\mbfp}{OT1}{cmss}{m}{n} \pagestyle{empty} \begin{document} \font\fontA=cmr10 $ \mbfa{A} \mbfb{B} \mbfc{C} \mbfd{D} \mbfe{E} \mbff{F} \mbfg{G} \mbfh{H} \mbfi{I} \mbfj{J} \mbfk{K} \mbfl{L\ fam=\the\fam\ } \mbfm{M} \mbfn{N} \mbfo{O} \mbfp{P} \ \textfont255=\fontA \fam255 roman $ \end{document} %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% log file はこんな感じです． %%%% LaTeX2e on LuaTeX での log %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% This is LuaTeX, Version snapshot-0.20.2-2007121821 (Web2C 7.5.6) (format=latex 2009.2.12) 12 FEB 2009 03:30 **test.tex (test.tex LaTeX2e <2005/12/01> Babel <v3.8h> and hyphenation patterns for english, loaded.
