Yes - exactly. I tried different ways but the sorting in the hierarchy file is always in ascending order. Is there any way to sort differently? If so, it would be easy to run the procedure twice to identify positions for nodes in each triad.

Positions within fragments are returned as an additional result
of fragment searching in Pajek (Vector) in case that positions are
'marked' in the fragment.
Positions which are interesting for us should be marked in fragment
with the label "1".

I looked to the hierarchy produced for the network
http://vlado.fmf.uni-lj.si/pub/networks/data/test/class.net
We get
+"Root" 0 0.000 33 ""
+"1" 0 1.000 3 ""
* 1
* 7
* 13
+"2" 0 1.000 3 ""
* 1
* 3
* 10
+"3" 0 1.000 3 ""
* 1
* 10
* 13
+"4" 0 1.000 3 ""
* 1
* 9
* 10
...
It seems that the problem could be solved by listing nodes
in the homomorphism order (and not ordered in ascending order):
the i-th node in the list corresponds to the i-th node in the
fragment. Then the first node will always be 2-out star, ...
The requested characteristics (tables) are then obtained from
the hierarchy by short procedures in R.
