In this work, the notion of orthogonal nonseparable quarternary wavelet packs, which is the generalization of orthogonal univariate wavelet packs, is introduced. The definition for orthogonal nonseparable quarternary wavelet packs is presented by iteration method. The orthogonality characters of quarternary wavelet packs are discussed. Three orthogonality formulas concerning these wavelet packets are estabished. Moreover, it is shown how to obtain new orthogonal bases of space from these wavelet packets.
