No, you've described, essentially, only one of the functions, and you have 5 left. To define a function on V, you must describe where each element gets mapped to by T. You could describe your first function there as (0,1,2) -> (0,1,2). Another function would be (0,1,2) -> (0,2,1). Do you know what the name is of this mathematical idea? That will help you get all the desired functions.
