EXAMPLE
After the initial zero, A037016 begins:
1
2 3
5 6 7
10 12 13 14 15
21 25 26 28 29 30 31
42 50 51 53 56 57 58 60 61 62 63
85 ...
and after resorting, A175020 begins:
1
2 3
5 4 7
10 12 9 8 15
21 ...
so the irregular table begins:
1 1
2 2 3 3
5 5 4 6 7 7
10 10 12 12 9 13 8 14 15 15
etc.
In binary, the number 9 maps to multiset (1,2,1) and the number 13 maps to (2,1,1), so 9 and 13 appear together in the sequence.
