The problem of simplicity of Fermat number-twins f_n^{plus or minus) =
2^(2^n){plus or minus 3} is studied. The question for what n numbers
f_n^{plus or minus) are composite is investigated. The
factor-identities for numbers of a kind x^2 {plus or minus} k $ are
found.

a(n) are (sorted) from Tarasov, p.5

If this is worth submitting, what is the next value a(5) asserted by
Tarasov to be equal or greater than (2^(2^17)) - 3?
