Category:Ill-defined

This category was deleted due to discussion, and hence you are not allowed to add pages to this category. If you want to add pages on ill-defined googological notions to this category, please add them to the following alternative categories: They are categories for googological notions which are known not to be completely defined. See also Category:Unsolved problems for googological notions which are not known to be well-defined. For example, a formalised system which is believed to be well-defined in Zermelo–Fraenkel set theory but has not been verified in Zermelo–Fraenkel set theory is suitable for this category and articles on Bashicu matrix system and Laver table belong to this category.
 * 1) Category:Unformalised. The category for googological notions which have not been completely defined due to the fact that they have not been formalised in a reasonable theory such as Zermelo–Fraenkel set theory or its extensions which are believed to be consistent. For example, large functions only admitting intuitive descriptions or intended behaviours are suitable for this category, and articles on BEAF and Sam's Number belong to this category.
 * 2) Category:Incomplete. The catrgory for googological notions which are currently ill-defined due to the fact that their definitions include serious errors or serious ambiguities. For example, a formalised system whose well-definedness implies contradiction is suitable for this category, and articles on BIG FOOT and Little Bigeddon belong to this category.
