U+03DB "ϛ" Greek Small Letter Stigma Unicode Character

U+03DB "ϛ" Greek Small Letter Stigma is a historical Greek letter that originated as a ligature of the letters sigma and tau, and it was used in ancient and medieval Greek writing to represent the number 6 in the Greek numeral system, though it should not be confused with the modern Greek letter stigma, which is a different character often replaced by the digraph "στ" in contemporary typography.
