%N Greatest number m such that the fractional part of (Pi-2)^A153718(n) <= 1/m.

%F a(n) = floor(1/fract((Pi-2)^A153718(n))), where fract(x) = x-floor(x).

%e a(3) = 38 since 1/39 < fract((Pi-2)^A153718(3)) = fract((Pi-2)^23) = 0.02600... <= 1/38.

%t A153718 = {1, 2, 23, 24, 35, 41, 65, 182, 72506, 107346};
