I've finally written all the scripts necessary to extract individual paths from minimal puzzles in T&E(n) to the inner side of the border with T&E(n-1).
In a previous post, I gave an example in T&E(3), and in another post I mentioned a puzzle in T&E(1) with a still longer path (18 steps) towards T&E(0). Here are now the details of this latter example.
Before that, I need to recall that it's the path that allows the maximum number of BRT-independent additions of clues, not necessarily the path with the largest BRT-distance to T&E(0). This longest path has 18 independent steps (but the BRT-distance of the minimal puzzle to the T&E(0) border is only 6.)
The last line below is the minimal puzzle. One must read upwards in order to see the successive additions of clues (alternating +p and +BRT). I've added manually the B (=W) ratings of the puzzles. It's noticeable that the minimal puzzle has a very low W rating (3) but can nevertheless be expanded so many times within T&E(0).
(A puzzle resulting of a BRT-expansion is not rated, as it can only have the same rating as the puzzle below it in the list.)

Needless to say that computations to obtain such results must explore unimaginably many paths within T&E(1) and take a very long time.
