"`And a b`, or `a ∧ b`, is the conjunction of propositions. It can be\nconstructed and destructed like a pair: if `ha : a` and `hb : b` then\n`⟨ha, hb⟩ : a ∧ b`, and if `h : a ∧ b` then `h.left : a` and `h.right : b`.\n\n\nConventions for notations in identifiers:\n\n * The recommended spelling of `∧` in identifiers is `and`.\n\n * The recommended spelling of `/\\` in identifiers is `and` (prefer `∧` over `/\\`).\n\n * The recommended spelling of `🥤` in identifiers is `bland`."
