An appropriate value of entropy for a charged and rotating black hole is obtained by calculating the partition function on thermal geodesics confined under horizons. The quantum aggregation is classified in a similar way to the Reissner--Nordstrom black hole.6 pages, 1 eps-figure, iopart class, acknowledgement extendedGeneral Relativity and Quantum CosmologyAstrophysicsHigh Energy Physics - Theorytext
