Neutron and absolute x-ray diffraction data obtained from single-phase icosahedral powder ${\mathrm{Al}}_{73}$${\mathrm{Mn}}_{21}$${\mathrm{Si}}_{6}$ are analyzed using a generalized Patterson autocorrelation function in three dimensions. The icosahedral pattern is quasiperiodic. The local atomic arrangements match those encountered in the prototypic crystalline \ensuremath{\alpha} phase. Extra peaks in the local icosahedral pattern match those of an icosahedrally rotated \ensuremath{\alpha} pattern.
