The trihex is equal to \(\lbrace6,6,6\rbrace\) or \(6\lbrace6\rbrace6\) in BEAF, \(6\uparrow\uparrow\uparrow\uparrow\uparrow\uparrow6\) in arrow notation, or 6 octated to 6.. The term was coined by Aarex Tiaokhiao. This is the sixth Ackermann number.
The name of this number is based on Greek prefixes tri- (three) and hexa- (six), meaning that there are 3 6's in the array.
