N2 - Using the data samples collected in the energy range from 3.773 to 4.600 GeV with the BESIII detector at the BEPCII collider, we measure the dressed cross sections as a function of center-of-mass energy for e+e-→K+K-π+π-(π0), K+K-K+K-(π0), π+π-π+π-(π0), and pp¯π+π-(π0). The cross sections for e+e-→K+K-K+K-π0, pp¯π+π-(π0) are the first measurements. Cross sections for the other five channels are much more precise than previous results in this energy region. We also search for charmonium and charmonium-like resonances, such as the Y(4230), decaying into the same final states. We find evidence of the ψ(4040) decaying to π+π-π+π-π0 with a statistical significance of 3.6σ. Upper limits are provided for other decays since no clear signals are observed.
