    We went through the Ackermann function before, here, Johan.

    Maybe it's time to go back to it again, and at least calculate, A(4, 2).

    [A(4, 3) = 2^2^65536 - 3.

    From within the REPL in DrRacket (using unlimited memory), I tried to execute,

    (define a (- (expt 2 (expt 2 65536)) 3)),

    and, DrRacket crashed.]
