About Quinary (Base-5) & Senary (Base-6)
Quinary (Base-5) and Senary (Base-6) are numeral systems used in various cultures around the world. Base-5 is often linked to counting on the five fingers of one hand and is found in languages like Gumatj (Australia). Base-6 systems, sometimes used alongside Base-12 or Base-24 systems, are present in some Papuan languages (e.g., Kopo) and Nigerian languages. These "small base" systems are fascinating because they demonstrate diverse, often body-based, methods of counting that evolved independently of the now-dominant decimal system.
