If I understand the recent messages from Howard Fink <fink at acf5.nyu.edu>, Peter Horan <peter at aragorn.cm.deakin.oz>, and John Mitchell <mitchell at pico.uchicago.edu>,and am not confused now :-), below is a simple example demonstrating a problem with the Collect[] function. Mathematica (sun3.fpa) 1.2 (November 6, 1989) [With pre-loaded data] In[1]:= Collect[(-1)^(-1+2n),x] (* note no x in first argument *) 2 n Out[1]= (-1) Mark Senn Purdue University mds at pop.stat.purdue.edu
