Oof, of course; very nice. What's more, starting with a 3-4-5 and rotating about the midpoints of the length 3 and 5 sides gets you one extra rational (integer, even!) value; you end up with {3, 4, 5, 13, 5*sqrt(145), sqrt(7081)}.
Sorry, MK --- this one is a dud, with no planar perms at all!
Er, well, yes. One does need to clear *all* one's denominators. How do you like {3*18, 4*18, 5*18, 13, 5*sqrt(145), sqrt(7081)} ? Triply planar, I hope. --Michael*18 Kleber -- It is very dark and after 2000. If you continue you are likely to be eaten by a bleen.
