The integration part of that is easy and sage can do it for a single
integer interval:
>>> a = var('a')
>>> assume(a, 'integer')
>>> integrate(2^2^floor(x), (x, a, a+1))
2^(2^a)
Now you just need the summation of that over the range of integer
intervals you are interested in but Sage's sum can't do anything with
that and I'm not sure if anything else can either.
