  We detail the construction of the most general asymptotically flat,
stationary, rotating, non-extremal, dyonic black hole of the four-dimensional
N=2 supergravity coupled to 3 vector multiplets that describes the STU model.
It generates through U-dualities the most general asymptotically flat,
stationary black hole of N=8 supergravity. We develop the solution generating
technique based on SO(4,4)/SL(2,R)^4 coset model symmetries, with an emphasis
on the 4-fold permutation symmetry of the gauge fields. We indicate how
previously known non-extremal and extremal solutions of the STU model are
recovered as limiting cases. Several properties of the general black hole
solution are discussed, including its thermodynamics, the quadratic mass
formula, the Bogomolny-Prasad-Sommerfield limit, the slow and fast extremal
rotating limits, its properties in regards to the Kerr/conformal field theory
correspondence, its Killing tensors and the separability of geodesic motion and
probe scalars.
