--- Comment #4 from noktastrigo at yandex.ru ---
There are 2^(2*n) tiles on zoom level n. So there must be 4294967296 tiles for
zoom level 16 to 16, 5368709120 tiles for zoom level 15 to 16, ..., 5726623056
tiles for zoom level 2 to 16 for the whole globe (from 85.0511 N to -85.0511
S). And on your screenshot there are much less tiles. Actually, 5726623056 mod
2^32 = 1431655760 - something around you've got.
