We study experimentally the reproducible conductance fluctuations between the quantum Hall plateaus in the conductance of two-terminal submicrometer silicon MOSFETșs. For the dramatic fluctuations at the insulator-to-first-plateau transition we find a conductance distribution that is approximately uniform between zero and (Formula presented). We point out that this is consistent with the prediction of random (Formula presented)-matrix theory for a conductor with single-channel leads in a magnetic field.
