U+1D2C4 "𝋄" Kaktovik Numeral Four Unicode Character

U+1D2C4 "𝋄" Kaktovik Numeral Four is a numeral from the Kaktovik Inupiaq base‑20 numeral system, which was invented in the 1990s by Alaskan Inupiaq school students to make arithmetic more intuitive and suited to traditional counting practices. The symbol itself is a simple horizontal line with three shorter marks above it, representing the number four in a system that combines a base‑20 structure with a visually positional logic where numbers are built from strokes and curves. It was added to Unicode in 2022 to support the preservation and digital use of the Kaktovik numeral system, reflecting a broader effort to encode indigenous and culturally specific numerical representations.
