%N Greatest number m such that the fractional part of (10/9)^A153696(n) >= 1-(1/m).

%F a(n):=floor(1/(1-fract((10/9)^A153696(n)))), where fract(x) = x-floor(x).

%e a(3)=15, since 1-(1/16)=0.9375>fract((10/9)^A153696(3))=fract((10/9)^13)=0.9341...>=1-(1/15).

%Y Cf. A153664, A153672, A153680, A153688, A153696, A154130, A153708, A153716, A153724.
