[seqfan] Re: 0-additive and first differences

[Frank Adams-Watters]

If I understand what's happening here, wouldn't we instead start

      1,3,7,12,18,10,19, ...
diff  2, 4, 5, 6,  8,  9

Hello SeqFans,
This is (I hope) the lexico-first 0-additive seq such
that
sequence and first differences list all positive numbers 
exactly once:

  
S = 1, 3, 7, 12, 18, 26, 17, 28, 41, 51, 37, 22, 47, ...
diff    2  4   5   6  
8   9  11  13  10  14  15 
25

Best,
É.
