Since TO's N is variable, that means that his "numbers" are variable too
so that which of two numbers is larger could depend on what the value of
N is at that moment, but cold change momentarily.

A TO-number starting with a zero and having infinitely many zeros
following it then a 1 then infinitely many more zeros then a final zero
must always be a part of his set, at least as he has described it.

But two such TO-numbers cannot be compared for size unless one is told
in advance which is larger or that they are equal.

Then 0:0000....000010000....0000 and 0:000...010...000 are both
properly defined "numbers" in TO-numerics, so there must be some rule
for determining from their representations which is larger.

So how does one tell, strictly from their representations, which is
larger?

0:0000....000010000....0000 and 0:000...010...000?

They are as organic as compost and no more mathematically relevant.
