Sets of integers containing no n terms in geometric progression
Published online by Cambridge University Press: 18 May 2009
Extract
R. A. Rankin [3] considered the problem of finding, for each integer n ≧ 3, a sequence of positive integers containing no n−term geometric progression. He constructed such sets Bn having asymptotic density
For example A3 ≑ 0·71975, A4 ≑ 0·8626, and An→1 as n → ∞.
