Digamma

  • abstract: Digamma (or wau, uppercase , lowercase ; as a numeral: stigma, ϛ) is an archaic letter of the Greek alphabet, which originally stood for the sound and later remained in use only as a symbol for the number "6". Whereas it was originally called wau, its most common appellation in classical Greek is digamma, while, as a numeral, it was called episēmon during the Byzantine era.
