# Term for repeated exponentiation?

Is there a term (or operation) for repeated exponentiation?

I.e. Repeated addition is multiplication, repeated multiplication is exponentiation, repeated exponentiation is X?

Is there even such a term for such a "higher order" operation, seeing as we could potentially deal with this by increasing the exponent?

at least if you are looking for something like $$\underbrace{a^{(a^{(\cdot^{\cdot^{a)\cdots)}}}}}_n$$
