Counting ordinal numbers from Ea1-1 we find that multiples of 32 are exceptional:

1 6
Ea1-14 Ea1-15 Ea2-32 (64) Ea2-33
2 7
Ea1-22 Ea1-23 Ea3-10 Ea3-11
3 8
Ea1-31 Ea1-32 Ea3-17 Ea3-18
4 9
Ea2-11 Ea2-12 Ea3-28 Ea3-29
5 10
Ea2-22 Ea2-23 Ea4-5 Ea4-6 (106)

Indeed, the sign 32 is insisted on also at Ea3-32 (where 3 * 32 = 96):

10
Ea3-30 Ea3-31 Ea3-32 (96) Ea3-33 Ea3-34 Ea3-35 (99)

Ea1-32 is depicted as only a 'ghost', Ea2-32 is ihe tau (death), and not until in the 10th period does a 'living canoe' enter into the text.

Line a1 has 32 glyphs (Ea1-32 is the last in the line), line a2 has 33 glyph (necessary in order to put Ea2-32 in its correct position), while line a3 has 35 glyphs - presumably to reach 99, which means line a4 will begin with 100 (as if a new season has been born).
