 OFFSET 0,1 COMMENTS Let c = (1/2)^(1/3). A sphere of radius c*r has half the volume of a sphere of radius r. - Rick L. Shepherd, Aug 12 2016 Let c = (1/2)^(1/3). The relative maximum of xy(x+y)=1 is (c,-1/c^2). - Clark Kimberling, Oct 05 2020 LINKS Clark Kimberling, Table of n, a(n) for n = 0..10000 FORMULA Equals 1/A002580 = A002580*A235362 = A005480*A020761.
