And so is the path of 1/pi distinguishable from all its finite initial

segments which are in the tree. But as you said, 1/pi is not distinct

from them. It comes into tze construction automatically. The limit is

in any case a member of the sequence. That is unmathematical.

Then explain why this is not possible in the Binary Tree. You said

that the irrationals come into the tree automatically, impossible to

distinguish by nodes.
