chicometica (T1871:1)
This is a notation for the number seven, chicome, consisting of seven circular, anthropomorphic suns (with faces and spiky auras) in a horizontal row. The reference is to seven days (tonalli). The -tica suffix, which says how often, every seven years, make the number into an adverb.

The suffix, -tica, is not unusual with numbers that refer to units of time, such as days and months. And this row of suns refers to seven days. See metztica, as another example, where a number of months (metztli) is the reference.
