Thanks!!! > You could use Transpose to get the lists of x- and y-coordinates, each in one list, and then find min and max; like this lst = Array[{Random[], Random[]} & , 10]; t = Transpose[lst]; (Max[#1] & ) /@ t (Min[#1] & ) /@ t Out[128]= {0.8925679798969234, 0.9646159435193661} Out[129]= {0.2203449244291362, 0.21003593197684423} Regards, Wolfgang
