Exoplanets orbiting pre-main-sequence stars are laboratories for studying planet evolution processes, including atmospheric loss, orbital migration, and radiative cooling. V1298 Tau, a young solar analog with an age of 23 +/- 4 Myr, is one such laboratory. The star is already known to host a Jupiter-sized planet on a 24 day orbit. Here, we report the discovery of three additional planets?all between the sizes of Neptune and Saturn?based on our analysis of K2 Campaign 4 photometry. Planets c and d have sizes of 5.6 and 6.4
