Let A(a,b,c) = S (11)^a (12)^b <D (11)^c 0^inf
* Rule 9: A(a, b, c) --> A(a, b - 1, 2c + 3)
* Rule 10: A(a, b, c) --> <math>A(a,0,2^{b} \times c + 2^{b} \times 3 - 3)</math> which becomes <math>A(a,0,2^{b+1} \times 3 - 3)</math> if c = 3.
* Rule 11: A(a, 0, c) --> A(a - 2, c + 3, 3)
Further: let <math>f(n) = 2^{n+1} \times 3</math>
* If c = 3: A(a, b, 3) --> A(a, 0, f(c) - 3) --> A(a - 2, f(c), 3)

The TM enters configuration A(19, 2, 3) after 799 steps with tape:
0^inf 2 1 (11)^19 (12)^2 <D (11)^3 0^inf
</pre>
==Trajectory==
A(19, 2, 3) --> A(19, 0, 21) --> <math>A(1, f^{8}(24), 3)</math>
--> <math>A(1, 0, f^{9}(24) - 3)</math>
Let's have <math> f^{9}(24) - 3</math> = m.

Let <math>f_1(n) = 2^{n+5}-3</math>
Let <math>f_2(a,b) = f_1^{2 \times f_2(a-1, b) + 11}(1)</math>, where<math>f_2(0, b) = b</math>
Rule 21 becomes:

* <math>D_1(a, b, c) --> D_1(a, b-1, 2^{b+5}-3)</math>

* <math>D_1(a, 0, c) --> D_1(a-3, 2c+11, 1)</math>
Rule 24 becomes:

Rule 25 becomes:

Rule 26 becomes:

Rule 27 becomes:

Rule 28 becomes:
* D(1, 0, c) --> halt with score 4c + 18
By repeating rule 21, a stronger rule can be constructed:
* <math>D(a, b, c) --> D(a, 0, f_1^{b}(c))</math>
* <math>D_1(a, b, c) --> D1(a, 0, f_1^{b}(c))</math>
If a is greater than or equal to 3:

* <math>D(a, 0, c) --> D(a-3, 0, f_1^{2c+11}(1))</math>
This rule can also be repeated, also note that <math>f_1^{2c+11}(1) = f_2(1,c)</math> and <math>f_1^{2 \times f_2(a,b) + 11}(1) = f_2(a+1,b)</math>:

f_1(2k+1) = 2^2k+6-3
Note that 2k+6 is of the form 2k, and that the whole expression is of the form 2k+1.
This means that any f_1^a(2k+1) = some f_1^a-1(2k+1)
Now consider that 2^2k mod 3 = 1 and 2^2k+1 mod 3 = 2
f_1(2k+1) = 2^2k+6-3
Note that 2k + 6 is of the form 2k, meaning that 2^2k+6 mod 3 = 1
The -3 will not affect the Modulus here, as it is a full cycle back to 1.
Thus f_1(2k+1) mod 3 = 1, and, by earlier f_1^a(2k+1) mod 3 = 1
f_2(a,b) = f_1^(2*f_2(a-1,b)+11)(1)
Note that f_1^(2*f_2(a-1,b)+11)(1) is also of the form f_1^a(2k+1)
Thus f_2(a,b) mod 3 = 1
