Numbers to ponder

Here are some numbers I have been looking at. They are very large. If you can figure out what they're supposed to mean, then kudos to you. I'll put up the full story, minus context, after finals are over. So in like a month. In the meantime, here are the numbers.
8^8 = 16777216
8^16 = 2.8147498*10^14
8! = 4032
8!^3 = 6.5548321*10^13
24*21*18*15*12*9*6*3 = 264539520 = 8!*3^8
24*21*18*15*12*9*6*3)^2 = 6.9981158*10^16
on another note
8^8*12^12 = 1.4958734*10^20
8^8*24^24*24^24 = 7.1922132*10^67
and, in conclusion,
(8!*3^8)(12!*2^12) = 5.1902404*10^20
(8!*3^8)(24!*2^24)(24!) = 1.7085268*10^63
