Music on the planet Alpha Lyra IV consists of only two notes, called A and B. Also, songs never include three consecutive repetitions of any sequence nor does BB ever occur. A sequence of notes can have 1 or more notes in it.

What is the longest song on Alpha Lyra IV?

So far, I'm seeing the use of the "groups" BA and BAA. I could be missing something but it looks like it might possibly be pretty long. You can't ever have AAA or even BB. Similarly, you can't have BA BA BA, BAA BAA BAA, and so on. However, it seems as though you can continually change the pattern in which you add notes. I don't feel like writing a program for it just yet.
