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?
I got the same 16 notes as Charlie
baabaababaababaa and its reversal by making a branching tree an nipping the buds that would cause 3 repetitions.
OK, Charlie. What about a third note called C where CC cannot occur. If this is infinite, what others such as BC could be excluded to bring it back to finite.

Yeah, but I did it by hand (and other questions)
