Experimental data obtained from 1974 to 1992 at the Yakutsk array for muons with threshold energies E{sub {mu}} {ge} 1 GeV in extensive air showers (EAS) are analyzed. Periods of reliable detector operation are selected, and miscounts of muon detectors near their operation thresholds are thoroughly taken into account. Average lateral distribution functions (LDF) are obtained for EAS muons in the energy range E{sub 0} = 10{sup 17} - 5 x 10{sup 19} eV and in the zenith-angle range {theta}=0{degrees} - 60{degrees}. For energies E{sub 0} > 5 x 10{sup 18} eV, the LDF are shown to depend on E{sub 0} and {theta} in a substantially different manner than they do in the range of lower EAS energies. This irregularity is apparently associated with certain unknown processes or unknown primary particles involved in the development of EASs. 7 refs., 13 figs.
