Entanglement certification with randomized measurements is the most resource-intensive task among all two-qubit invariants because it requires the maximum number of measurement settings.
In this case the statement requires an easy modification of the proof of Proposition C.1, since onlyN ⊗2 3 ̸= 0and its prefactor is now s1s2s3√ 2 6
