Thanks to everyone who responded to the problem with Word's
Array formula command.  An overwhelming majority suggested
I dump the formula approach and use a drawing program to
construct the commutative diagram.  In the end, it worked
out, however.

The key idea came from idsardi@athena.mit.edu (thanks Bill!)
who used nested Array structures to overcome Word's apparent
inability to handle more than 39 arguments in a single Array
command (a documented bug?).

Here's the end result (I hope this single, long line comes
thru unscathed):

\A(\A\ac\hs0\vs0\co8(,,,,f,,,),\A\ac\hs0\vs0\co8(,A, <190>,\D\ba1()<190>,\D\ba2()<190>,\D\ba2()<174> ,A,),\A\ac\hs0\vs0\co8(,\S\di-2\do2(<189>),,,,,\S\di-2\do2(<189>),,h ,\S\di-3\do3(<189>),,,,,\S\di-3\do3(<189>), h,,<175>,,,,,<175>,,,B, <190>,\D\ba1()<190>,\D\ba2()<190>,\D\ba2()<174> ,B),\A\ac\hs0\vs0\co8(,,,,g,,,))

Cut and paste this beast, and make the following changes:

1) replace all backslashes with the formula character (use
   ^\ in Word's Change utility);

2) replace the forms <nnn> with the corresponding ascii char-
   acter taken from the Symbol font (use command-option-Q);

3) italicize the function and set names;

4) edit out the \hs0\vs0 options if you wish (I was hoping
   to use negative spacing options, rather than \D, to line
   up the arrows and bars, but this doesn't work).

I stored mine in a Mathematics Glossary formatted with the
Normal style (except for the Symbol characters) so that the
resulting structure takes on the font of the surrounding text.

I dare say it looks pretty good!

Thanks again for all the help,
