[seqfan] a(a(n))=a(n)+a(n-1)

[Eric Angelini]

Hello Seqfans,
another 'self-describing' seq asking if it is
worth entering the OEIS:
S = 0,2,4,6,7,10,13,9,22,17,12,29,23,15,38,...
Again, "always use the smallest available
integer not leading to a contradiction"

Starting with 1 instead of 0 we get:
S = 1,3,4,7,6,13,11,9,20,12,24,32,19,15,...

Best,
E.
