They can be regarded as for instance a formation of (10 + 10) + 6:

Gb7-5 (416) Gb7-6 Gb7-7
Gb7-8 Gb7-9 (420) Gb7-10 Gb7-11
Gb7-12 Gb7-13 Gb7-14 (425)
Gb7-15 (426) Gb7-16 Gb7-17
Gb7-18 Gb7-19 Gb7-20 Gb7-21
Gb7-22 Gb7-23 Gb7-24 (435)

At Gb7-24 we can count 7 * 24 = 168, and ordinal number 24 indicates this is a day of Saturn. A bent Moon type of henua could maybe identify the end of a cycle, but we would then expect its curvature to be in the other direction (formed like the waning moon). Perhaps, therefore, this henua is meant to be the left half of a pure. If so, then next half ought to be henua in Gb8-13 (a day of Mercury):

19
Gb7-24 (435) Gb8-13 (455) pure
435 = 15 * 29 455 = 5 * 91

Otherwise there are no pure glyphs in G. 20 glyphs is the distance between these 2 henua glyphs. 7 * 13 = 91 = 364 / 4, and Gb8-13 could therefore indicate where a '5th quarter', a quarter for 'fire-making', is ending.

The position at ordinal number 436 (counted from Gb8-30) is occupied by the last one of those glyphs which I have classified as ika hiku in G, and it has no horizontal 'legs'. Primarily, though, it seems to be a variant of vaha mea:

Gb7-25 (436) Gb7-26 Gb7-27 Gb7-28
Gb7-29 Gb7-30

There are 472 glyphs all together in the text, and 472 = 400 + 2 * 36. 400 - 364 = 36 and 472 = 364 + 3 * 36 = 364 + 108:

35 35 35
Gb5-10 Gb6-17 (400) Gb7-25 (436) Gb8-30 (472)
364 108 = 3 * 36

Maybe we should continue further backwards in time taking 36 glyphs per step:

35 35 35
Gb1-26 Gb3-1 (292) Gb4-7 (328) Gb5-10 (364)
256 = 8 * 32 108 = 3 ' 36

This seems quite convincing. 472 = 4 * 64 (the season of growth) + 6 * 36 = 216 (the season of 'straw'). With two cycles in a 'year', it is not enough to 'square' one circle - two circles must be 'squared'. The black-and-white chessboard has 64 fields to illustates the season of growth (governed by Moon), but to measure Sun you need 6 (or 2) triangles:

It might be argued that the season of Spring Sun should be counted by Sun and not by Moon. However, it is the female Moon who governs the growth on the fields. It does not matter if Sun was the one who impregnated. Down in the black earth it is like the inside of the womb of a woman.

The season of 'straw' must then be measured by Sun, which can be easily explained. During the season of 'leaf' attention is focused on the growing fields while during the season of 'straw' attention is instead focused on the lack of Sun and the need to light fires down on earth.

Another argument possibly raised by my imaginary opponent is the 'obvious' mismatch between a square and a hexagon. To answer I need an extra page.
