Until the release of Alan Sasaani's book A Maadamadika Di-Syana in 1831, only the numbers one to one-hundred were standardized and agreed upon. It was this book that also led to the arabic numerals (which were already widely used in Syana) to become the official numerals of Syan. The number system is almost certainly a product of the number of digits humans have, twenty in total spread out in fives across four limbs. This is reflected in the "core" 20 digits of Syan.
