Octal value (base 8).
Convert binary directly to octal. Each three binary bits map to a single octal digit, so this is the natural representation when grouping by triples — common in Unix permission systems.
Why does 111 become 7?
Each three-bit group corresponds to an octal digit: 111 → 7, 110 → 6, 101 → 5, and so on.
