(Wiknik: "human being". Represents totality of his digits.)
The Yucatec number words reveal a clear vigesimal (base 20) structure with an embedded decimal layer evident in the numeration from 13 through 19.
There are two, possibly 3, layers in maya numerology. 20 on top of 13, on top of five for written numbers.
