	    Tribbles have litters of ten every twelve hours, and are
	capable of reproducing from birth.  Spock has the right number
	for the assumptions you list.  However, he also says that he was
	allowing for the limited amount of space and food in the
	compartment, but the figure he gives doesn't reflect that, nor
	should it be possible to do so exactly.  It turned out there
	weren't that many of them anyway, because of the virus in the
	quadrotriticale.
