Double exponential function

A double exponential function is a constant raised to the power of an exponential function. The term hyper-exponential functionThe Fz, The Fuga & The Megafuga by Sbiis SaibianUltimate Large Numbers List by Sbiis SaibianGoogo- and Googolple- Part 1: Two curious prefixes by Cookiefonster is also used, although that term can also refer to tetration. Examples include:
* Double Mersenne numbers
* Fermat numbers

* The number of non-self-crossing paths in a game of as a function of the number of discshttps://oeis.org/A125295
* The suffix -duplex/-plexplex/-plexian/-plusplex
* The fuga- prefix also falls around that range, although it is slightly faster.
