http://www.psypokes.com/rselgfr/gvguide.php is where I found the unknown factor.
I believe it was the ID of a pokemon in your party at the start of the day must match the Mirage Number. Traded pokemon have different ID numbers than yours so the number of possibilities are between 1,200,000 and 153,600,000, depending on whether the gender number must match or whether the gender must match. WOW!!!
EDIT on July 16, 2008: Sorry, Serebii was the only site I used until June this year.

Psypoke has that information. Please do not link to outside sites (especially serebii) if Psypoke has that information already.
