 OFFSET 1,2 COMMENTS Since A003022 is the most important sequence dealing with Golomb rulers, it seems best to define this sequence in terms of that one. Original name was: Maximum label within a minimal labeling of 2 identical n-sided dice yielding the most possible sums. For example, two hexahedra labeled (1, 3, 8, 14, 17, 18) yield the 21 possible sums 2, 4, 6, 9, 11, 15, 16, 17, 18, 19, 20, 21, 22, 25, 26, 28, 31, 32, 34, 35, 36. No more sums can be obtained by different labelings, and no labeling with labels < 18 yields 21 possible sums. Therefore a(6) = 18. Bounded above by A005282. - James Wilcox, Jul 27 2013 Minimum greatest integer in a set of n positive integers with all the differences between any two of its elements being different. - Javier Múgica, Jul 31 2015 LINKS CROSSREFS Cf.
