Can you give a list for factorization for Phi(n,2), like this factorization for Phi(n,2) for n<=1280, but for larger n, or the base 2 analog of https://stdkmd.net/nrr/repunit/Phin10.txt?

The Main tables for the Cunningham Project give all that is known as of October 13, 2020 for 2^n - 1 and 2^n + 1, odd n < 1300; 2^n + 1, n = 4k-2, n < 2600; and 2^n + 1, n = 4k, n <= 1300.

I'm not sure about what's known for n > 1300, apart from factors found for specific reasons, as in this thread.

All known factors should be available in factordb.

Have all exponents <= 13372531 (the largest known Wagstaff exponent, found in 2013) been tested?
