Here, the unexpected appearance of a fractional quantum Hall effect (FQHE) plateau at ν = 2 + 6/13 offers a clue into the physical mechanism of the FQHE in the second Landau level (SLL). Here we propose a “ $$\bar{3}$$ $$\bar{2}$$111” parton wave function, which is topologically distinct from the 6/13 state in the lowest Landau level. We demonstrate the $$\bar{3}$$ $$\bar{2}$$111 state to be a good candidate for the ν = 2 + 6/13 FQHE, and make predictions for experimentally measurable properties that can reveal the nature of this state. Furthermore, we propose that the “n$$\bar{2}$$111” family of parton states naturally describes many observed SLL FQHE plateaus.
