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.
