%N Least k where Phi(k) has height greater than k^n, where Phi(k) is the k-th cyclotomic polynomial and the height is the largest absolute value of the coefficients.
%C Arnold & Monagan compute this sequence to demonstrate their fast algorithm for computing cyclotomic polynomials.
%C This sequence is infinite because (the supremum of) A160338 grows exponentially.
