Let Oi (i=1,2,3,4,5) be the concyclic 4L-Circumcenters (4L-n-P3).
Let Hi be the anticenter of Oj.Ok.Ol.Om, where (i,j,k,l,m) are different numbers from (1,2,3,4,5).
H1, H2, H3, H4, H5 are concyclic on a circle with center 5L-s-P4.
The lines Hi.Oi (i=1,2,3,4,5) have a common point 5L-s-P5.
5L-s-P5 divides 5L-n-P3.5L-n-P7 as well as Hi.Oi (i=1,2,3,4,5) in parts (1:2).
There is a remarkable resemblance in a 4-Line where QL-P5 is dividing Hi.Oi (1:1).
