Compose T6 with all

(dolist (x '(t1 t2 t3 t4 t5 t6 t7 t8 t9 t10 t11 t12))
   (print (list 't6 (list x (t6 (funcall x r))))))

We get the results:

(T6 (T1 ("abaBABAAbbb" . "AbbbA"))) 
(T6 (T2 ("babABA" . "AbbbA"))) 
(T6 (T3 ("aabaBABA" . "AbbbA"))) 
(T6 (T4 ("abaBAB" . "AbbbabaBABA"))) 
(T6 (T5 ("abaBAB" . "aBBBa"))) 
(T6 (T6 ("abaBAB" . "bbbAA"))) 
(T6 (T7 ("babaBABB" . "AbbbA"))) 
(T6 (T8 ("abaBAB" . "abAAbbA"))) 
(T6 (T9 ("baBABa" . "AbbbA"))) 
(T6 (T10 ("abaBAB" . "AAbbb"))) 
(T6 (T11 ("BabaBA" . "AbbbA"))) 
(T6 (T12 ("abaBAB" . "aBAAbbbbA")))
