Right, I was looking at that when I made my comment. It says it's a
variant of Recaman's sequence, and shows the similar computation, but
it doesn't explicitly show the relationship I mentioned.
I have now submitted this as a new formula.

the exact relationship to Recaman's sequence: a(n+1) = A005132(n)+1.
It already says:
%N A063733 A variant of Recaman's sequence: a(0)=1, a(n) = a(n-1)-(n-1)
if
positive and ne\
