"Megistron" redirects here. It is also an alternative name for octalogue.

Megiston is equal to ⑩ in circle notation[1], or 10 in a pentagon in Steinhaus-Moser notation. The name was coined by Hugo Steinhaus along with the mega in his book Mathematical Snapshots as "The reader may try to explain the 'Megiston' given by ⑩."

There is some confusion over the correct spelling of the number. Weisstein misspells it as megistron[2] in a MathWorld entry, and Jonathan Bowers misspells it as megaston.[3] Even more confusingly, "megistron" is also an alternate name for octalogue.

Approximation[]

In up-arrow notation, megiston is between \(10 \uparrow\uparrow\uparrow 11\) and \(11 \uparrow\uparrow\uparrow 11\).[4]p.18 in preprint By using continuous arrow notation, \(11 \uparrow\uparrow\uparrow 11 \approx 10 \uparrow\uparrow\uparrow 11.00776\).

Therefore megistron is very closely approximated by \(f_4(10) \approx 10 \uparrow\uparrow\uparrow 11.00426\) using FGH.[5]
