Two-length wavelets are either minimum-delay or maximum-delay wavelets. We can pair every two-length wavelet with another two-length wavelet - namely, its reverse . Such a pair is called a dipole. One of the members of the dipole is a minimum-delay wavelet and the other is a maximum-delay wavelet. The minimum-delay wavelet is the one that has the larger coefficient (in magnitude) at the front, whereas the maximum-delay wavelet is the one that has the smaller coefficient (in magnitude) at the front.
