Later, in 1891, Cantor used his more familiar diagonal argument to prove the same result.

Cantor's diagonal argument shows that the set of such numbers is uncountable.

The paradox can be interpreted as an application of Cantor's diagonal argument.

A different proof of is given in Cantor's diagonal argument.

For an elaboration of this result see Cantor's diagonal argument.

His proof is more complex than the more elegant diagonal argument that he gave in 1891.

A variety of diagonal arguments are used in mathematics.

His proof does not use his famous diagonal argument, which he published in 1891.

And yet Cantor's diagonal argument shows that real numbers have higher cardinality.

This appeals strictly to set theoretical notions, and is thus not exactly the same as Cantor's diagonal argument.
