Symbolic dynamics of a piecewise rotation: case of the non symmetric bijective maps

We consider a specific piecewise rotation of the plane that is continuous on two half-planes, as studied by some authors like Boshernitzan, Goetz and Quas. If the angle belongs to the set $\{\frac{\pi}{2},\frac{2\pi}{3},\frac{\pi}{4}\}$, we give a complete description of the symbolic dynamics of this map in the non symmetric bijective case.
