Do you mean a 'mapping'?
i.e.
1 -- 4
2 -- 3
3 -- 2
4 -- 1
Where -- means 'maps to'.
Or do you want to arrange the bits so that there is always a different
result after the operation?
i.e.
1 -- [0..0x]
2 -- [0..0x]
...
Any ouput is valid given an integer input.

Easy to guess is relative.
Actually, any mapping from int to int is an (equally) easy one to
guess. The encryption part would be to change the mapping on each int
or sequence of ints by a rotation or equation.
int - int ( '-' represents a map from one to another)
Provides 0x possibilities
