or ...

I also found this:

The Golden Exponent?  Any idea what this mysterious symbolism means?

NO! That is NOT the answer. No calculator can calculate it!! According to WolframAlpha, this is its representation as a power of 10s:

10^(10^(10^(10^(10^(10^5.842593328962333))))). However, they do give the last few digits as

.........1565172343.

But that is powers of TEN...  not powers of SEVEN.

And this online high precision calculator website:

did calculate it.

Yes, they do give an answer, but it is totally wrong!!. The powers of 10 given by Wolfram are equivalent to the tower of 7s. You start from the right to the left like this: 7^7^7^7^7^823,543 =7^7^7^7^(3.75982352  E+695974). The power of the 4th 7 is more than 695,974-digit long!! And so on......etc.
