Probably tired or plain retarded, but I've been wrecking my head and I can't fucking solve this shit.
AB = 12345
BA = 54321
ABA = 123454321
BAB = 543212345
BAAB = 5432112345
ABBA = 1234554321
AABB = ?
1234123455
>1234123455
is wrong.
the correct answer is 1234432155, sorry took two tries
I'm going for 1123455
but I could come up with a few other "solutions"

AABB = 1123455.
s/A/1/g
s/B/5/g
s/15/12345/g
s/51/54321/g

From A to A, then to B, then to B.
>1123455
Then multiply it by one, one being (ABA/ABA) and make AABB/ABA = B, therefore B/ABA, which is 1/AA. Knowing that from A to A is 1 -> 1, 1/AA=1. This is proof that if AB and ABA are right, then AABB=1123455 is right.
I think it's 1123455 too.
A is "1", B is "5" and whenever you go from A to B you count "234" and vice versa from B to A "432". So AA would be two 1, then BB two 5, and a count in between.
It's 1122334455.
