In C the birth of a new moon coincides with reaching number 168, and at 192 full moon is reached:

Ca6-25	Ca6-26	Ca6-27	Ca6-28	Ca7-1
165	166	167	168	169

Ca7-21	Ca7-22	Ca7-23	Ca7-24
189	190	191	192

The resemblance with the structure in K is remarkable. Sun disappears when 168 is reached:

Kb4-11	Kb4-12	Kb4-13	Kb4-14 (167)
Kb4-15 (168)	Kb4-16	Kb4-17	Kb4-18

The last step of the sun on the mainland is 167, but then - it seems - the new moon comes in to save the situation. But she lasts only for 24 nights (192 - 168 = 24), then her decline comes.

In G number 168 is located in another position among the glyphs in parallel with those of K:

29
	Ga6-27 (168)	Ga6-28	Ga6-29
30
	Ga7-1 (171)	Ga7-2	Ga7-3	Ga7-4
31
	Ga7-5	Ga7-6	Ga7-7 (177)	Ga7-8	Ga7-9	Ga7-10

Nga Kope Ririva (at 6 * 29.5 = 177) lies outside the mainland, in the domain of the moon. Sun is to the left in maitaki in Ga7-8.

Extending the investigation to Tahua, where we probably have to change from 168 to 2 * 168 = 336, we find:

Aa4-78	Aa4-79	Aa4-80	Aa4-81	Aa4-82	Aa5-1	Aa5-2	Aa5-3
329	330	331	332	333	334	335	336
165		166		167		168

And looking at 2 * 177 = 354 (Aa5-21) respectively 2 * 192 = 384 (Aa5-51):

Aa5-18	Aa5-19	Aa5-20	Aa5-21	Aa5-22	Aa5-23	Aa5-24	Aa5-25
351	352	353	354	355	356	357	358
176		177		178		179

Aa5-46	Aa5-47	Aa5-48	Aa5-49	Aa5-50	Aa5-51	Aa5-52	Aa5-53
379	380	381	382	383	384	385	386
190		191		192		193

We should notice that ihe tau glyphs appear at or closely preceding the redmarked glyphs.
