In the case of the i-ching it's literally six bits of binary (expressed in yarrow stalks).
In genetic codons there's four symbols instead of two, and three places instead of six, so the effect is the same. (Does base 4 have a name?)

Kind of. And as a guy with a solid science background, I just don't buy into that kind of interpretation.
But if it is numerology, I believe I CHING divination is more like a commit-and-reveal scheme — you can't infer the future from the proof alone. You might only get to verify it once the future actually plays out. Kind of like a zero-knowledge proof — it gives you a proof/advice based on a possible future, but you gain nothing from it since the underlying computation is NP-hard. So better to treat it as a kind of thinking framework — like SWOT or scenario planning, but from a different cultural tradition.
