By using electron diffraction method, three new vacancy ordered phases, τ23,τ27 and τ35, have been found in the conventionally solidified Al65Cu20Co15 alloy. They do not belong to the known Fibonacci series The computed kinematical intensities shown that the stacking sequences of τ23,τ27 and τ35 are respectively 332323232, 3323323323 and 3323323323323.
