1 + 20 + 168 + 45 = 234 (Gb1-5). 144 + 92 + 1 = 237 (Gb8-30). 234 + 237 = 471. The numbers say, though, that we should rearrange 4 * 36 one step ahead:

	20		166		46		142		91
Ga1-1		Ga1-22		Ga7-19		Gb1-7		Gb5-26		Gb8-30
		1		168		1		144
		4 * 42				4 * 36

1 + 20 + 168 + 46 = 235 (Gb1-6). 144 + 91 + 1 = 236 (Gb8-30). 235 + 236 = 471. It seems logical not to start at Gb1-6 because we did not start at Ga1-26. As to the number 42 and 36 the number of glyphs in A is 628 + 42 = 670 on side a and 628 + 36 = 664 on side b. 42 is used on the 'light' side and 36 on the 'dark' side. 46 (the distance between Ga7-19 and Gb1-7) also agrees with Tahua because 1334 = 46 * 29.
