There are over 4 novemquinquagintillion (4 with 180 zeroes after it) possible permutations of this map, or about 400000000000000000000000000000000000000000000000000000000000000000000000 times the number of atoms in the universe. Thank you to @Zocker_Welt for figuring most of that out. HOWEVER: Tiles are more likely to be the same as tiles next to them, so there are still the same amount of permutations, but some are more likely than others.
