Hexteto

Visualization of boogasix using exponentiation

Boogasix is equal to \(6\uparrow\uparrow\uparrow\uparrow6\), or six hexated to 6.

Googology Wiki user Hyp cos call this number hexteto, and it's equal to s(6,6,4) = s(6,2,5) = s(6,4,1,2) in strong array notation.[1]

EtymologyEdit

The name "boogasix" is formed by applying the booga- prefix to 6.

The name "hexteto" is based on the word "hexa" and "tetra" (Greek for 6 and 4), meaning a base-6 number, generated using hyper-4 operation based on exponentiation.

ComputationEdit

Boogasix can be computed in the following process:

  • \(f(1)=6\)
  • \(f(2)=6^{6^{6^{6^{6^6}}}}\) with f(1) 6's, a.k.a. megafugasix
  • \(f(3)=6^{6^{\vdots^{6^6}}}\) with f(2) 6's
  • \(f(4)=6^{6^{\vdots^{6^6}}}\) with f(3) 6's
  • etc.
  • Boogasix equals \(f(f(f(f(f(6)))))\).
