Let’s consider the combination of azimuth which can be detected by the rotation of octagon.
Turn octagon on 1 degree counterclockwise. In this position we get with the error of 0.08 azimuth of Holy mountain- pyramid - Kailash.
From the direction to Kailash, according to the angles of octagon is located azimuth of Samaipata.
Angle between the directions is 67.47degrees, the error is 0.03.
Then turn the octagon clockwise. Turning the octagon on 6.5 degrees we obtain already known to us the line of Solomon temple- Angkor – Easter island from which the angle close to 22.5 degrees is away azimuth of Lalibela.
Between Solomon temple and Lalibela are 22.26 degrees (-0.24). Between angles of Easter island and Lalibela are 22.17 degrees (-0.33).
Having turned octagon on 12 degrees clockwise we obtain ,with accuracy of 0.05, azimuth of Teotihuacan from which on 44.32 degrees (-0.68) is away azimuth of Sigiriya which lies on meridian of Teotihuacan.
To be more precise this is the angle between the directions to Sigiriya and antipode of Teotihuacan.
Rotation on 14.5 degrees clockwise gives directions to St. Petersburg and Nazca desert. The angle between the azimuths is 112.75 degrees (+0.25).
