The effect of incommensurate potential on Fermi surface (FS), which loses any translational symmetry in the energy bands, is investigated in the organic superconductor (MDT-ST) (I3) 0.417, where MDT-ST is 5H -2-(1,3-dithiol-2- ylidene)-1,3-diselena-4,6-dithiapentalene. The observed three fundamental Shubnikov-de Haas oscillations are explained by the reconstruction with the three times of the incommensurate anion periodicity. This unambiguously verifies the selection rule of the reconstructing vectors in incommensurate crystals. The angular magnetoresistance oscillations show that the FS has a p -type staggered corrugation with two nodes in the interlayer transfer integral.
