Your Subject field is spelled correctly, but your article has some
apparent typos:

(Do you mean "an" instead of "and"?)

Assuming those typos fixed as I suggested, there are two issues
involved here: The string of digits you are trying to express, and any
number if any which is thereby expressed.
Let's tackle an easier and well-defined example first:
0.1000000000... (with an infinite amount of trailing zeroes)
That notation has a clear meaning. There is an infinitely long array of
digits, indexed by 0, -1, -2, -3, ... (I'm using negative indexes so
the power of ten matches the index rather than the negative of the
index, reserving positive indexes for any digits to the left of the
units position, which doesn't apply here, but would apply with other
examples using the same notational system.)
digit[0] = '0'
digit[-1] = '1'
digit[-n] = '0' for all other values of n (2,3,4,...)
The set of digits is of ordinality -omega, i.e. like omega but running
the opposite direction (from 0 downward into negative integers instead
of upward into positive integers).
But in your case, it's not clear what your set of indexes for the
digits are supposed to be? How do you put an infinite number of indexes
*between* two fixed endpoints, while still having the digits near
either fixed endpoint be descrete like a sequence or reverse sequence?
Like it's easy to get this part:
0.0000
with indexes 0, -1, -2, -3, and -4,
and this part:
0001
with indexes N+3, N+2, N+1 and N, for some abstract symbol N,
but how do you get an infinite number of digits between them?
..............
What set of indexes for those digits are you presuming?
After you answer that question, *then* we might be able to find any
meaning to those digits representing any number.
