Fig 9. Boolean co-abundance patterns and logical operations.

Fig 9

The remaining six possible Boolean operations - here shown for completeness - do not provide any further information. Copying the first entry into the first entry (j1) is the identity operation and leads to no change at all. Copying the j2 entry into j1 leads to a change but only copies existing abundance information. Setting the output bit always to one (last row) conveys zero information such that the output is simply number of samples α, β, γ, δ. The other three operations are just logical complements thus likewise convey no additional information.
