Sequence of Musical Tones (Posted on 2004-12-14)

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?

(In reply to re: computer solution by Charlie)

what if aaa was still not allowed, but bb was allowed (though not bbb)??

I don't have an answer, I'm just curious.
