The mass quantum and black hole entropy II

In gr-qc/9908036 [Phys. Lett. A 265 (2000) 1] a new method was given which naturally led to a quantum of mass equal to twice the Planck mass. In the present note which, for convenience, we write formally as a continuation of that paper, we show that with spin one of the mass quantum, the physical entropy of a rotating black hole is also given by the Bekenstein-Hawking formula.
