N2 - Using data samples collected by the BESIII detector located at the Beijing Electron Positron Collider, the cross sections of the process 푒+⁢푒−→푓1⁡(1285)⁢휋+⁢휋− are measured at 45 center-of-mass energies from 3.808 to 4.951 GeV. An investigation on the energy-dependent cross section is performed, and no significant structure is observed.
