The isotope was synthesized in the complete fusion reaction of $^{40}$Ar beam ions and $^{208}$Pb target nuclei. The neutron yields of $^{246}$Fm spontaneous fission ($\\overline{\\nu} = 3.79\\pm0.30$, $\\sigma^{2}_{\\nu} = 2.1$) were obtained using the SFiNx detector system. The multiplicity distribution of emitted prompt neutrons was restored using the Tikhonov method of statistical regularisation ($\\overline{\\nu}_{r} = 3.79\\pm0.20$, $\\sigma^{2}_{\\nu r} = 2.8$).
