I'm trying to typeset

$one \sideset{}{_{three}}\prod two$

as $one \sideset{}{_{three}}\prod two$ in instiki (well, ok, it's the nLab [waves to Andrew Stacey]), but it doesn't work. Is there any other alternative to \sideset that I could use?

The \fourIdx command from the fouridx package could be an option; no idea if it works in instiki, though. –  Gonzalo Medina Apr 13 '11 at 0:52
    
I've also tried \nolimits to no avail –  David Roberts Apr 13 '11 at 0:56
    
@David: This site doesn't have math-tex, since most of the time we're discussing the TeX itself, not the math. I took the liberty of embedding the desired image in your question. –  Antal S-Z Apr 13 '11 at 5:52

not sure why you're using \sideset. the following gives the same result as what is shown in the question: $one \displaystyle\prod\nolimits_{three} two$ and if there's something else in the math string that you don't want in \displaystyle`, just wrap the middle section in {...} to localize it. –  barbara beeton Apr 13 '11 at 14:13

For those that don't know: Instiki is a wiki designed specifically to be suitable for mathematics. For that, it uses a program called iTeX to convert a subset of LaTeX to MathML. The nLab is a project that uses Instiki. Relevant links: instiki, itexToMML, and nLab. –  Loop Space Jun 17 '11 at 15:03

*waves back*

This is probably off-topic (as iTeX is only based on a subset of TeX, not a TeX package or format), but there is an answer that is similar to a LaTeX solution which is to use the \tensor command. In LaTeX this is supplied by the tensor package. In iTeX, it is one of the implemented commands.

$one \tensor{\prod}{_three} two$

Produces:

tensor command in Instiki

(I missed this first time around, sorry. Happened to search for instiki here and spotted this. Probably better posted on the nForum.)

Thanks! I have been slack at looking at SEv2 sites so missed your response. Now I can't remember where I was doing this! –  David Roberts Jul 5 '11 at 2:22
