I tried a few arrays, and all crashed my Excel (55k rows is a heck of a lot
of rows). I would say just use a Pivot Table; there is almost no limit to the size of the data parameters that you can deal with.

This is relatively fast:
=COUNT(1/FREQUENCY(A1:A55000,A1:A55000)) Many of the other methods of doing this require arrays, and when you deal with lots of rows (i.e. 55k rows), things slow down to a speed that is quite simply intolerable...
