We have a set of natural numbers, so called line-numbers of necessary findable lines. This fact does not mean that theset of so called line-numbers of necessary findable lines is nonemptyand has a least element.I understand that an empty set need not and can not have a leastelement. What I not yet understand is that an empty set can house morethan zero elements, in fact more than one.But with this premise accepted, set theory is certainly not provablyinconsistent.Regards, WM
