[seqfan] Selfdescribing reordering of N

[Eric Angelini]

First lexicographically reordering of the naturals
such that the digitsum of any a(n) is visible in a(a(n)):

1,2,3,4,5,6,7,8,9,10,12,13,14,15,16,17,18,19,100,20,
23,24,25,26,27,28,29,101,11,30,34,35,36,37,38,39,
102,110,112,40,45,46,...

Example:
"12" says that 3 (digitsum 1+2) is visible in
the 12th term of S (which is true, the 12th
term being 13.

Best,
