> I am looking for a big times operator entity

unicode.xml (in the source zip file linked from the mathml spec, or a
newer version at http://www.w3.org/2003/entities/xml


<character id="U02A09" dec="10761" mode="math" type="large">
 <entity id="xtimes" set="STIX">
 <description unicode="3.2">N-ARY TIMES OPERATOR</description>

so the character you are looking for is <mo>&#x2a09;</mo> but having a
slot for that character in Unicode isn't the same thing as meaning that
the fonts used for your mathml rendering have automatic mappings so that
this unicode character works as expected.

One day (this year, hopefully) the stix fonts will arrive which will
make it feasible to have a default font for all the Unicode mathematical
characters so that you should be able to use any such character without
worry, but currently you need to test on your system.

Note that the set of characters with entity names in the MathML DTD
isn't the same thing as the set of characters that are supported in any
particular system. Typically some without names will be supported, and
perhaps also some with names will not be supported. It all depends which
fonts you have.
