Hello SeqFans,
I'm having troubles with https://oeis.org/A128204
0, 1, 4, 9, 2, 11, 22, 35, 20, 3, 22, 43, 66, 41, 14, 43, ...
I see two times "22" and two times "43" here. Is it allowed?
Shouldn't the sequence start:
0, 1, 4, 9, 2, 11, 22, 35, 20, 37, ... with a new definition?
(like: erase the last term leading to a contradiction and try
adding instead of subtracting? Such a term would be "3", in
the above sequence).
----------
This new definition would be useful to compute a Recaman's
variation I don't see in the database -- the "Recaman's
transform of the even numbers":
1 3 7 13 5 15 27 41 25 43 23 45 21 47 19 49 (and not 11)
2 4 6 8 10 12 14 16 18 20 22 24 26 28 30 32 ...
Best,
É.
