The energy gap due to anion ordering introduces essential differences for electrons of two particular subbands in a magnetic field. The magnetic breakdown restores the behavior of the prototype ${\mathrm{PF}}_{6}$ in an irregular manner as the field increases. The fast oscillations (periodic in 1/H) appear to be due to the fact that the electron trajectories in ${\mathrm{ClO}}_{4}$ coincide with those in ${\mathrm{PF}}_{6}$ only at specific values of H. The fast oscillations superimpose on the cyclotron-resonance-type singularities.
