 OFFSET 1,1 COMMENTS The word "below" in the definition is somewhat ambiguous. More precisely, this is the list of n such that A065188(n) < n. - N. J. A. Sloane, Aug 18 2016 For Greedy Queens that do not attack along antidiagonals, the analogous sequence of indices is A026352. LINKS N. J. A. Sloane, Table of n, a(n) for n = 1..19098 EXAMPLE Greedy Queens take positions (1,1) (2,3) (3,5) (4,2) (5,4) (6,9) ... and the 4th and 5th are below the main diagonal, so a(1)=4 and a(2)=5.
