The article said the best classical factoring algorithms are O(e^N). The author presumably meant theta rather than O. The General Number Field Sieve [1] is significantly faster than that, with a running time of theta(exp(((64/9)*log N)1/3 (log log N)2/3). I've changed the sentence to claim superpolynomial rather than exponential. --LC
