Websurprisingly similar to Tannakian reconstruction; we will prove the theorem following the proof of Tannakian reconstruction (for, say, groups). The proof written in this way is similar to the one used by Riley [Ril18]. Theorem 3. Let U (A;B): ˜ !Sets the functor that evaluates a Tambara module on the object (A;B).
