Driven IFS with Forbidden Combinations:

T₄ never immediately follows T₁

If T4 never immediately follows T1, then no points land in the square T4(S1) = S41.

Because S41 contains no points, the subsquares T1(S41) = S141, T2(S41) = S241, T3(S41) = S341, and T4(S41) = S441 cotain no points.

Continuing, here are the pictures showing the subsquares of address length 4 (left) and 5 (right) containing no points.

The pattern should be clear:

no points lie in any subsquare with address containing 41.
