+ed4/3 has good approximations of [[5/4]] and [[11/10]] (the latter from [[3ed4/3]]) and their fourth-complements [[16/15]] and [[40/33]]. Treated as a 4/3.5/4.11/8 temperament, it tempers out the commas [[4000/3993]] and [[5632/5625]], a structure that is identical to [[Escapade family#2.3.5.11 subgroup|escapade]]. [[32/31]] can additionally be added as a representation of a single step, tempering out [[961/960|S31]] and [[1024/1023|S32]].
