A geometric representation of the group of nonextensive entropy vectors in four-dimensional space is derived. The three-dimensional hyperbolic entropy vector and the vector-parameter of hyperbolic angles are determined. A composition law for hyperbolic entropy vectors with quadratic nonlinearity is given and an interrelationship with three distributions characterizing the system is presented.
