(which self-describe their sizes)
Look at A:
A =
1,10,3,4,5,6,7,8,9,11,21,12,31,13,14,110,15,41,16,17,18,112,19,20,51,100,101,201,102,22,23,24,211,...
Now insert a vertical stroke between all
consecutive 1’s:
A = 1,10,3,4,5,6,7,8,9,11,
21,12,31,13,14,110, 15,41,16,17,18,112,
19,20,51,100,101,201,102,22,23,24,211,...
A = 1|10,3,4,5,6,7,8,9,1|1,21|12,31|13,14,1|10,15,41|16,17,18,1|12,19,20,51|100,101,201|102,22,23,24,21|1,...
The quantity of digits between two strokes
is given by A itself:
A = 1|10,3,4,5,6,7,8,9,1|1,21|12,31|13,14,1|10,15,41|16,17,18,1|12,19,20,51|100,101,201|102,22,23,24,21|1,...
1 10 3
4 5 6 7 8 9 11
A is the lexicographically first such
sequence; to build it we always use the smallest available integer not yet
present in A and not leading to a contradiction.

Look at B:
B =
3,1,22,20,4,5,6,7,8,9,10,11,12,13,14,15,122,16,17,18,19,21,23,24,25,26,220,322,30,32,27,28,42,29,...
We insert now a vertical stroke between all
consecutive 2’s:
B = 3,1,22,
20,4,5,6,7,8,9,10,11,12,13,14,15,122, 16,17,18,19,21,23,24,25,26,220, 322,
30,32,27,28,42,29,...
B = 3,1,2|2|20,4,5,6,7,8,9,10,11,12,13,14,15,12|2,16,17,18,19,21,23,24,25,26,2|20,32|2,30,32|27,28,42|29,...
Again, we see that the quantity of
digits between two strokes is given by B itself:
B = 3,1,2|2|20,4,5,6,7,8,9,10,11,12,13,14,15,12|2,16,17,18,19,21,23,24,25,26,2|20,32|2,30,32|27,28,42|29,...

Now C:
C =
2,3,30,33,1,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,23,31,20,21,22,24,25,26,27,28,29,32,34,35,36,37,333,40,330,39,331,41,43,300,40,53,301,...
We insert our vertical strokes between all
consecutive 3’s:
C = 2,3,30,33,
1,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,23,31,20,21,22,24,25,26,27,28,29,32,34,35,36,37,38,333, 40,330, 39,331, 41,43,300,40,53,301,...
C = 2,3|30,3|3,1,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,23|31,20,21,22,24,25,26,27,28,29,32,34,35,36,37,38,3|3|3,40,3|30,39,3|31,41,43|300,40,53|301,...
As usual, the quantity of digits between
two strokes is given by C itself:
C = 2,3|30,3|3,1,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,23|31,20,21,22,24,25,26,27,28,29,32,34,35,36,37,38,3|3|3,40,3|30,39,3|31,41,43|300,40,53|301,...

Etc.
Could someone be so kind to compute a
hundred terms or so for A, B, C and the remaining sequences:
D = 4|4
E = 5|5
F = 6|6
G = 7|7
H = 8|8
I = 9|9
J = 0|0
