You start with a completely crystal clear statement: The antidiagonal number is not equal to any number on the list. Then you paraphrase this clear statement to get a completely muddled statement: >the antidiagonal comes up with an actual NEW SEQUENCE OF DIGITS >and this does not contradict that ALL sequences of digits are on >the computable list of reals up to all (an infinite amount of) >digit positions Why do you prefer to use muddled, incoherent statements instead of clear ones? The antidiagonal is not equal to any of the numbers on the list. What is unclear about that? -- Daryl McCullough Ithaca, NY

You claim this works on infinite lists. You claim no list contains EVERY DIGIT SEQUENCE because you can find a NEW DIGIT SEQUENCE But the computable real list contains EVERY DIGIT SEQUENCE up to all (an infinite amount of) finite lengths. EVERY DIGIT SEQUENCE POSSIBLE UP TO INFINITY! BELOW IS A *VALID* DIAGONAL ARGUMENT 123 456 789 DIAG = 159 ANTIDIAG = 260 See how it actually generates a NEW SEQUENCE OF DIGITS!!!!!!!!!!!!!!!! Your argument doesn't do that! Here is what is ACTUALLY happening. 1 Start with a list containing all sequences. 2 Find a NEW sequence 3 CONTRADICTION Herc

Yes it does. If you start with a list that exists you get a new sequence of digits. (E.g. if you start with a list of sequences, every one of which has a last digit, you get a sequence that does not have a last digit). > > Here is what is ACTUALLY happening. > 0.
