Set.powersetCard.faithfulVAdd

∀ {α : Type u_2} [inst : DecidableEq α] {G : Type u_3} [inst_1 : AddGroup G] [inst_2 : AddAction G α] {n : ℕ},
  1 ≤ n → ↑n < ENat.card α → ∀ [FaithfulVAdd G α], FaithfulVAdd G ↑(Set.powersetCard α n)

If an additive group G acts faithfully on α, then it acts faithfully on powersetCard α n, provided 1 ≤ n < ENat.card α.
