Original Wikitext content:
Semaphore, namesake of the [[Semaphore family]], is characterized by the vanishing of 49/48, so the generator represents 8/7 and 7/6 equally. This results in a very low complexity 2.3.7 temperament, with the drawback that most intervals of 7 must be out of tune by at least half of 49/48, or about 18 cents.
If 5 is mapped at all, it makes sense to map it to -8 generators by tempering out 81/80, making it a meantone temperament. This temperament is called "godzilla".
