The ground floor is numbered as 1, the floor just above it is numbered as 2 and so on till the top most floor is numbered as 4. Each floor has 3 flats in it i.e., flat 1 and flat 2 and flat 3. Flat 1 of floor 2 is immediately above flat 1 of floor 1 and immediately below flat 1 of Floor 3 and so on. Flat 2 of Floor 2 is immediately above flat 2 of floor 1 and immediately below flat 2 of Floor 3. In the same way, flat 3 of Floor 2 is immediately above flat 3 of floor 1 and immediately below flat 3 of Floor 3 and so on. Flat 1 is exactly to the west of Flat 2 which is exactly to the west of flat 3. R lives on an even numbered floor to the south east of U. P lives just above U’s flat. Two floors gap between T and P. Y lives two floors above T and lives to the east of W. T lives in prime numbered flat and to the south east of X. X doesn’t live in odd numbered flat. S lives to the north west of Z. S and O live on the same floor. V lives below Q. X lives in the south of U.

Question:
How many floor(s) gap is/are between O and T?
