I have recently found a problem and I don't know what this notation means.The problem says : find all the triples (x,y,z) for which {(x-y)/(y-z),(y-z)/(z-x),(z-x)/(x-y)}={x,y,z}.I don't understand what {x,y,z} means.Thanks in advance!]]>http://www.mathisfunforum.com/profile.php?id=2134112017-01-02T13:58:21Zhttp://www.mathisfunforum.com/viewtopic.php?pid=392731#p392731
