- diffhist Ring (mathematics) 11:06 −35 Quondum talk contribs (Undid revision by Goodphy – the lack of a requirement for some property is not a property, and that wording had the implication that invertibility is a property of the integers. If you really feel that the lack of the invertibility requirement must be stated in the lead (to be clear, I do not: the integers are clearly not invertible), say it in a way that makes sense.)
