That was an excellent organic chemistry question, however. I suspect that most organic chemists with a PhD (I have one) would never have come up with 16 without having to explicitly write out all the racemates (and maybe not even then), or even understood why there were 4 dienes rather than just three since there are only 3 isomers of methyl cyclopentadiene.
