Playing the five-year-old game, what's Mag(n) & Gag(Gag(...(n))? As many Gags as N, to get it back to a function of one variable. Or as many Gags as Gag(n), or as many Gags as Mag(n)...)
  —Alistair Cockburn

Mag is a function devised by Alistair Cockburn (of fuga- glory) in one of his forum pages, considering how a five-year-old might extend gag by indicating repeated application after learning this function. \(Mag(n\) is defined as \(\underbrace{\mathrm{gag}(\mathrm{gag}(\mathrm{gag}(\mathrm{gag}(\ldots n\ldots))))}_n\), using the gag function.[1] He also never used mag (along with gag) as a prefix despite rumors of him doing so; the prefix form was coined by Sbiis Saibian, also known for coining booga-[2].

It is comparable to \(f_{\omega + 1}(n)\) in the fast growing hierarchy. Notably, \(mag(64) > g_{64}\) where \(g_{64}\) is Graham's number.
