Description: Anything implies ⊤. Dual statement of falim 1554. Deduction form of tru 1541. Note on naming: in 2022, the theorem now known as mptru 1544 was renamed from trud so if you are reading documentation written before that time, references to trud refer to what is now mptru 1544. (Contributed by FL, 20-Mar-2011.) (Proof shortened by Anthony Hart, 1-Aug-2011.) |
