Now turn octagon on 5.5 * clockwise. In this position, we can see that azimuths of Nan Madol, Angkor, Sigiriya, temple of Solomon and St. Petersburg on Easter island are located according to octagon. Thus, two pairs of objects together with EI lie on one line.
Turning hexagram we determined that EI, Sigiriya and St. Petersburg lie on the same line. Now, thanks to octagon, we see that between this line and the direction to Angkor are 45 *, with the error of 0.51 *.
The angle between the direction to St. Petersburg and Angkor is 44.35 * the error is 0.65 *. Between azimuths of Nan Madol and Angkor is respectively half 45 * or 22.17*, the error is 0.33 *.
Now let's see how azimuths of these objects interact in other points. In Nan Madol azimuths of Sigiriya and St. Petersburg are located according to hexagram, between them are 60 *. The angle between azimuths of Angkor and St. Petersburg is close to the angle of pentagram  54 *. At that azimuths of EI, Sigiriya and St. Petersburg are located multiply to 20 *, i.e. according to nonagon.
In the point of Sigiriya azimuths of EI, St. Petersburg, of Nan Madol and Angkor are located according to nonagon multiply to 5 *.
In the point of Angkor azimuths of Sigiriya and EI also interact according to nonagon, between them are 40 *. It should be noted also that Angkor together with Great Pyramid are almost equidistant from the EI. As far as Angkor are 16240 km, to GP are 16166 km.
In its turn, temple of Solomon (ST) together with Por Bajin are also equidistant from EI. Distances are 16550 and 16540 km, respectively. Approximately the same distance is from Easter Island to Baalbek  16660 km and Plain of Jars  16592 km.
Besides, in the point of ST line EI  ST  Angkor with the small error is eastwest direction, i.e.is perpendicular to the North. direction.
As it mentioned in the article "GEODESY OF ST.PETERSBURG." Palace Square has a very precise orientation to Nan Madol, which azimuth is equal to 53 *. Azimuth of Nan Madol in St. Petersburg interacts with azimuth of Angkor also according to octagon between them are 45 *.
