“…We mention some prior results confirming the formal degree conjecture for inner forms of GL n and SL n [HII08b], unipotent discrete series representations of adjoint unramified groups [Ree00, CKK12, Opd13], depth-zero supercuspidal representations of pure inner forms of unramified groups [DR09], [HII08b,§3.5], and certain positive-depth supercuspidal representations of tamely ramified groups [GR10, RY14,Kal12]. The formal degree conjecture is also known for U(3), GSp 2 , Sp 2 [GI14], and Mp 1 [Qiu12].…”
