COMMENTS

See A187224.  A187482 is the rank transform of (A004523 with initial zeros removed).

Is this a duplicate of A026347?

seqA = Table[Ceiling[2n/3], {n, 1, 180}] (* A004523 *)

seqB = Table[n, {n, 1, 80}];             (* A000027 *)

jointRank[{seqA_, seqB_}] := {Flatten@Position[#1, {_, 1}],

Flatten@Position[#1, {_, 2}]} &[Sort@Flatten[{{#1, 1} & /@ seqA,

{#1, 2} & /@ seqB}, 1]];

limseqU = FixedPoint[jointRank[{seqA, #1[[1]]}] &, jointRank[{seqA, seqB}]][[1]]                                   (* A187482 *)

Complement[Range[Length[seqA]], limseqU]  (* A187483 *)
