A super market uses an alpha-numeric code (using letters of the alphabet and numbers) of length four. Each code is handwritten and contains two distinct letters in between two distinct digits or vice versa. Since the code is handwritten, the letters H, I, M, N, O, S, W, X and Z and the digits 0, 1, 6, 8, 9 can potentially cause confusion when read upside down, (i.e., the code can be confused with another one when it is seen upside down) for example, the code M86X appears as X98W. How many codes are there for which such confusion can arise, given that there is no confusion between letters and numerical symbols.
