Okanran (|| || || |) is the second Odu on the list of the sixteen principal Odu of Ifa divination system. It has three double lines in the first three positions and a single line in the fourth position.
Since a double line represents the split side of a cowrie and a single line the smooth side, Okanran is comprised of three split sides of three cowries in the first three positions and a smooth side of a cowrie in the fourth position.
A split side of a cowrie is equal to 0, and its smooth side is equal to 1. Therefore, the three split sides are equal to 000 and Okanran is equal to 0001.
A cowry is a binary number comprised of 0 (split side) and 1 (smooth side). And an Odu is equal to 4 bits (binary digits). 0001 is a 4-bit binary numeral.
