I should have added some de-commutations:
(123) = [(412),(253)] = [[(341),(152)],[(125),(543)]] = [[[(234),(451)],[(315),(542)]],[[(312),(245)],[(154),(423)]]] = [
  [[[(123),(354)],[(245),(531)]],[[(231),(145)],[(154),(432)]]],
  [[[(431),(152)],[(124),(435)]],[[(215),(534)],[(142),(253)]]]
]
as in Decommute.nb.
