Abstract:
We study the relationship between iterated factorials, the iterated Euler gamma function, and iterated exponentiation. We demonstrate that both the iterated factorial and the iterated gamma function can be represented as a power tower, where all the terms are identical except for the top term. Additionally, we show that the top terms of this representation form a converging sequence. Finally, we prove that this representation can be reversed.
