*I* provide the List of All Reals.

*I* guarantee all possible segments are listed, in every possible
order.

PROOF BY INDUCTION.

BASE STEP
A(n) All 10^n segments occur in segment position 1, 2, 3,...
infinitely many times each in each position.

INDUCTIVE STEP
If <s1> <s2> are 2 consecutive listed segments in BASE STEP
< s11 s12 s13... s1m s21 s22 s23 .. s2n>

where m is the length of segment 1
and n is the length of segment 2

is ALSO a segment of the BASE STEP

Therefore by Induction, all sequences of all segments are listed.

GIVEN SUCH A LIST IN SEGMENTED FORM

LIST
R1= < <314><15><926><535><8979><323> ... >
R2= < <27><18281828><459045><235360> ... >

R5= < <0123456789><0123456789><01234 ... >
R6= < <1><414><21356><2373095><0488> ... >
....

You cannot calculate a missing anti-diagonal in *any* segmented form.
