	title={Factors of Generalized {Fermat} Numbers},
	abstract={A search for prime factors of the generalized Fermat numbers $F_n(a,b)=a^{2^n}+b^{2^n}$
		has been carried out for all pairs $(a,b)$ with $a,b\leq 12$ and $\gcd(a,b)=1$.
		The search $k$ limit on the factors, which all have the form $p=k \cdot
		2^m+1$, was $k=10^9$ for $m\leq 100$ and $k=3 \cdot 10^6$ for $101\leq
		m \leq 1000$. Many larger primes of this form have also been tried as factors
		of $F_n(a,b)$. Several thousand new factors were found, which are given
		in our tables. For the smaller of the numbers, i.e. for $n\leq 15$, or,
		if $a,b\leq 8$, for $n\leq 16$, the cofactors, after removal of the factors
		found, were subjected to primality tests, and if composite with , searched
		for larger factors by using the ECM, and in some cases the MPQS, PPMPQS,
		or SNFS. As a result all numbers with $n \leq 7$ are now completely factored.},
