The octomega is equal to M(8,3), using the Hyper-Moser notation M(m,n) for m inside n+2-gon. The term was coined by Aarex Tiaokhiao. In the up-arrow notation octomega is between \(8 \uparrow\uparrow\uparrow 9\) and \(8 \uparrow\uparrow\uparrow 10\). Octomega can be also expressed as ⑧ in the circle notation.
