- The nth (homogeneous) tower is and a nested exponential is .

- The nth tetrate is , and a (heterogeneous) tower is .

Anyone care to vote?

a) "Tower of height n", n'th tetrate (the latter, if context of continuous operation is focused), heterogeneous, leave "nested" for some more special cases (though I have no idea actually)

b) @Jay: top exponent, initial exponent; preferring "initial" to connect to iteration-theory("initial state") and due to the opportunity to be able to better talk about infinite towers and their fixpoints then.
