For the record, Adams said it was just a coincidence that it worked out that way in base 13. His intention was to write something humorous and off the wall. That it turned out to be mathematically accurate was purely serendipitous.

It was a one in three to one in four chance of an integer base
36 : 6x9 in base 16
37 : no integer base solution
38 : no integer base solution
39 : 6x9 in base 15
