 OFFSET 1,1 COMMENTS Conjecture: the difference sequence of A206911 consists of 2s and 3s, and the ratio (number of 3s)/(number of 2s) tends to a number between 3.5 and 3.6. Similar conjectures can be stated for difference sequences based on jointly ranked sets, such as A206903, A206906, A206928, A206805, A206812, and A206815. LINKS Table of n, a(n) for n=1..59. EXAMPLE Let S(n)=1+1/2+1/3+...+1/n and L(n)=log(n+1). Then L(1)
