Hello SeqFans,
could someone please check and compute a few more terms of S?
Each term of S "says":
--> The a(n)th term of S is 2*a(n)
To build S, always take the smallest available integer not
leading to a contradiction:
n = 01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 ...
S = 2 4 1 8 6 12 9 16 18 11 22 24 14 28 17 32 34 36 20 40 23 44 46 48 26 52 29 56 58 31 62 64 ...
Best,
É.
