مولف فایل pdf من بودهام. اگر فایل pdf را دارید، باید فایل تک را نیز داشته باشید. به هر حال این کدی است که نیاز دارید:

% Here, we find another nested use of \step inside \step.
% \bstep is a variant of \step which _always_ puts its argument into a box for leaving the correct amount of
% white space. We cannot use \parstepwise here because \put can't go into a box. Hence, just using \step for
% building the nested formula on the next line would give the wrong size for the nested braces.

دستورات کلیدی در اینجا دستورات \stepwise و \step هستند که در کلاس bidipresentation که باز هم من مولف آن هستم تعریف شدهاند.
