5G-s-P9 5G-Schmidt Point

Let P1P2P3P4P5 be a Pentagon.
The 5 circles through each set of 3 consecutive vertices have 5 further intersections Q1,Q2,Q3,Q4,Q5 denoted by Qi (i=1,2,3,4,5).
There are 5 circles (Qi, Pj, Pj+1) (i=fixed, j=1,...5) of which 2 coincide with one of the other circles. The centers of the 3 remaining circles form a new circle, called Qi-circle in the drawing.
There are 5 Qi-circles (i=1,2,3,4,5).
The 10 mutual radical axes of these 5 Qi-circles have a common point 5G-s-P9.
This point was found by Eckart Schmidt. See Ref-66, QPG-messages #612, #624.
