Ṣàwárí

Each Odù is two columns of four marks, every mark single or double, giving four bits per column, eight bits in total, and exactly 256 possible signatures.

What Ifá is, how the divination actually works step by step, how the binary structure produces 256 addresses into a memorised corpus, and what is true and false in the claim that it is an ancient computer.

The 256 Odù of Ifá are generated by a real, precise binary procedure, four marks in each of two columns, each mark one of two states. That structure is genuine mathematics, and it is also not proof of anything beyond itself.
