U+1D2CD "𝋍" Kaktovik Numeral Thirteen Unicode Character

U+1D2CD "𝋍" Kaktovik Numeral Thirteen is a symbol from the Kaktovik numeral system, a base-20 numerical notation originally developed in the 1990s by Iñupiaq students and educators in Kaktovik, Alaska, to visually represent their language's counting structure. This specific character depicts the number thirteen by combining elements that show one full group of twenty minus seven, or through its own unique linear strokes that correspond to the Iñupiaq word for thirteen. The Kaktovik numerals were formally added to the Unicode Standard in 2021 to support digital preservation and revitalization of the Iñupiaq language and its mathematical heritage, with this character serving as an essential component for recording larger quantities in the vigesimal system.
