=        (2^2401)^7)^7 -1
=          (2^16807)^7 -1
= 2^117649 - 1

Which is considerably smaller than 2^43112609 - 1, the current largest known prime.

And weren't you saying there were no numbers larger than 2^128?

Plan on ever answering questions or giving a clear description of just what it is you're talking about?
