NAME

Greatest number m such that the fractional part of (4/3)^A154130(n) <= 1/m.

DATA

3, 6, 10, 30, 124, 238, 405, 6430, 22869, 32657, 224544

OFFSET

1,1

FORMULA

a(n):=floor(1/fract((4/3)^A154130(n))), where fract(x) = x-floor(x).

EXAMPLE

a(3)=10 since 1/11<fract((4/3)^A154130(3))=fract((4/3)^13)=0.09238...<=1/10.
