Aa5-7	Aa8-26	Ab1-1	Ab7-26
Although quite similar they are nevertheless not exactly alike. Ab1-1 is harmoniously drawn, but shorter than Ab7-26. Aa8-26 has a thick bottom 'tail' end, whereas Ab7-26 contrariwise has a thick upper 'tail'. Aa5-7 and Aa8-26 are drawn as if deformed. Neither the top part nor the bottom part in Aa5-7 is thick, and the glyph is slightly bent forward, as if it was old.

The distance measured in glyphs from Aa8-26 to Ab1-1 is 60 and between Ab1-1 and Ab7-26 the distance is 520 glyphs. Let us instead say that 60 is measured beyond Aa8-26 up to and including Ab1-1 (which, of course, also must give 60):

	59		520
Aa8-26	59	Ab1-1	520	Ab7-26
-	*580 = 20 29**			-

The viri glyph type is connected with 29, and the distance between Aa8-26 and Ab7-26 is 20 * 29 = 580. A definite proof of viri being associated with 29 is delivered when we complete the cycle and measure from Ab7-26 up to and including Aa8-26:

	752
Ab7-26		Aa8-26
*754 = 26 29**

We recognize the numbers (20, 26, 29, 46) from the structure of the K calendar. The number of glyphs in Tahua is (20 + 26) * 29 = 1334.

But the 4th viri, Aa5-7, what function has it?
