Page 198: From Wikipedia (https: //en.wikipedia.org/wiki/Digamma):
Digamma, waw, or wau (uppercase: Ϝ, lowercase: ϝ, numeral: ϛ is an archaic letter of the Greek alphabet. It originally stood for the sound /w/ but it has principally remained in use as a Greek numeral for 6. Whereas it was originally called waw or wau, its most common appellation in classical Greek is digamma; as a numeral, it was called episēmon during the Byzantine era and is now known as stigma after the value of the Byzantine ligature combining σ-τ as ϛ ....
In modern Greek, this is often replaced by the digraph στ.
