=== Metaolympic ===
Metaolympic is a [[weak extension]] of olympic (tempering out [[5776/5775]]), requiring the split of the prime 7 in half; or alternatively, the septimal comma or the garischisma. It is better without prime 17, but prime 17 can be added easily into the temperament by also tempering out 4200/4199, which also takes advantage of the split prime 7, at the cost of higher error.
