Petersen, Uwe Dialetheias and numbers distinct from themselves. (English) Zbl 07720265 Notre Dame J. Formal Logic 64, No. 2, 239-246 (2023). Summary: According to Priest, a proof can be distinct from itself in the same way that a number can. Priest does not specify any such number, so the present little note aims at filling this lacuna by providing a plain arithmetical code of a dialetheia similar to but simpler than the one presented in our recent work and thereby a natural number distinct from itself.
