To reach the 3rd vaega glyph in line Aa2 we need to move into another 'territory', beyond 29 Ahu Akapu. Yet, a kind of continuity definitely can be perceived:

Aa2-28	Aa2-29	Aa2-30	Aa2-31	Aa2-32
Aa2-33	Aa2-34	Aa2-35	Aa2-36	Aa2-37	Aa2-38
Aa2-39	Aa2-40	Aa2-41	Aa2-42	Aa2-43
Aa2-44	Aa2-45 (135)	Aa2-46	Aa2-47	Aa2-48

If we compare with the other two we can see that vaega at right in Aa2-45 is drawn to be like vaega at right in Aa2-18:

					26
Aa2-14	Aa2-15	Aa2-16	Aa2-17	Aa2-18		Aa2-45 (135)
4				28

A further discussion is needed in order to locate vaega in Aa2-45 'on the map'.
