5L-s-P4: 5L-Center of the Anticenter Circle


Let Oi (i=1,2,3,4,5) be the concyclic 4L-Circumcenters.
Let Hi be the Anticenter (see Ref-13) 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.
Hi.Oi (i=1,2,3,4,5) have a common point. See 5L-s-P5.
See Ref-34, QFG#1904.
 5L s P4 Center Anticenter Circle 01

Properties:

5L-s-P4 is the midpoint of 5L-n-P3 and 5L-n-P7.
• Radius O-circle = 2 * Radius H-circle.
• The distribution of H-Points on the H-circle is similar to the distribution of O-points on the O-circle. They represent the angles between the defining lines of the 5-Line. See Ref-34, QFG#1893.
