Four superdeformed bands, consisting of [gamma]-ray cascades of up to 15 transitions, have been found in the light rare earth nucleus [sup 133]Pr. This is the first observation of multiple superdeformed bands in the [ital A][approx]130 mass region. These bands are populated weakly at 0.2%--1% of the reaction channel intensity. The single particle configurations have been identified as [pi][ital g][sub 9/2]9/2[sup +] for bands 1 and 2 and [pi][ital h][sub 11/2][532]5/2[sup [minus]] for bands 3 and 4. Dipole linking transitions between two superdeformed bands have been observed, branching ratios have been measured, and [ital B]([ital M]1)/[ital B]([ital E]2) ratios deduced. A [ital B]([ital M]1) value for the [pi][ital g][sub 9/2]9/2[sup +] orbital of (1.7[plus minus]0.2)[mu][sup 2][sub [ital N]] (where [mu][sub [ital N]] is the nuclear magneton) has been extracted, based on the measured quadrupole moment for the [sup 132]Ce core.
