COMMENTS

S is built with the rules [1] that you cannot insert any integer between two "touching" runs (run 1,3 is followed by 4,6,8,10,12; there is no integer between 3 and 4) and [2] that S and T share no integer.

T encodes the instructions for S.

It is not quite clear to me if T is the complement of S, or is merely disjoint from it.
