I'm not sure quite what you mean by combinatorial numbers? Do you mean "n choose m" notations for the number of combinations choosing m items from n, if sothere's an example to get (m) (n) notation using mfrac in the mathml spec in chapter 3. <mrow> <mo> ( </mo> <mfrac linethickness="0"> <mi> a </mi> <mi> b </mi> </mfrac> <mo> ) </mo> </mrow> If you want the m C n notation you would use msubsup with a C in the base. There is no standard Content MathML element for this, but you could use <csymbol>choose</csymbol> together with a stylesheet or mathml semantics element specifying one of the above presentation mathml forms for display.
