The 12 pages that link to Cantor's diagonal argument, each with the reason it gives.

• Georg CantorBroader topic: Cantor used it to prove that real numbers cannot be listed in a sequence.

• CardinalityRelated: Cantor used it to prove that the real numbers are uncountable.

• Countable setRelated: It establishes the uncountability of the real numbers directly.

• Transcendental numberRelated: Related counting arguments show transcendental numbers vastly outnumber algebraic numbers.

• Cantor's theoremBroader topic: Applied to subsets, it produces a subset missing from any proposed list.

• DiagonalizationBroader topic: It is the classic construction: change the nth digit of the nth listed number.

• Diagonal argumentBroader topic: Its digit-by-digit construction is the best-known instance of the diagonal method.

• Diagonal lemmaCompared with: It shares the diagonal name but proves non-enumerability rather than formal self-reference.

• Infinite setRelated: It proves that the real numbers cannot be listed, establishing an uncountable infinite set.

• Uncountable setRelated: Cantor used it to prove that real numbers cannot be completely listed.

• Schröder–Bernstein theoremRelated: Diagonal arguments often establish one-way cardinal bounds that the theorem can complete.

• Cardinality of the continuumRelated: It proves that no list of real numbers can exhaust the continuum.
