Googology Wiki:André Joyce archive/Gex

Gex is the name for the one-argument Ackermann function, A(10), a contraction of the two-argument function, A(10, 10), a contraction of the three-argument function, g(11, 10, 10) = g(12, 2, 10), ten-dodekated-to-the-second, with a verbalized -x-, so as not to be confused with Joyce's gox aka giji.
