Abstract
We identify the states in string theory which are responsible for the entropy of near-extremal rotating four-dimensional black holes in N = 8 supergravity. For black holes far from extremality (with no rotation ), the Bekenstein-Hawking entropy is exactly matched by a mysterious d uality invariant extension of the formulas derived for near-extremal b lack holes states.
