The n's for which the nth line of the list is not a FIS of d depends on the list and the d, so
Show me your list and I will show you a 'd' such that
NO line of the list is a FIS of 'd'. > > > > Since for every line of length n, d is of length at least n+1, at least > > everywhere else besides Wolkenmuekenheim, WMs claim does not hold true > > outside it. > > For every line of lenght n there is a line of length n^n^n, so d of > legth n+1 has no problems with accomodation. > > > > And inside Wolkenmuekenheim all lines are finite. > > Do you know of an infinite line?

But not any l longer than d, or even as long, if each l is finite.
The point is that for any listing of binary sequences, finite or infinite, one can define a diagonal which is not listed.
And no matter how loudly WM screams that it is not so, it remains so. --
