chicuetecpantli (Osu2v)
This simplex glyph and notation for the number 160 (chicuetecpantli) comes from the Codex Osuna folio 2 verso (image 7). It consists of two groups of four flags, connected at their bases by a horizontal line, for a total of eight (chicuei). The flags (pamitl, whose root, -pan- is part of the -tecpantli) represents the number twenty. The flags are flying toward the viewer’s right. The flag posts are painted tan, suggestive of wood, while the flags (paper or fabric?) are left white.

The mathematical equation here is 8 x 20 = 160. A flag (pamitl) used to be held up by a labor boss who was in charge of gathering and supervising 20 men (or groups of 20). This may be how it came to be equated with the number twenty, which is the base of the vigesimal numbering system of the Nahuas. See two examples of the macuiltecpanpixqui labor boss, below, who held up five flags (5 x 20) that called for 100 laborers.
