I wrote a program to do the counts.
It's very slow (it was designed for ease of programming, not for
speed of execution), but at least it's automatic.
For n = 1, 2, 3, 4, 5, I get the counts
2, 7, 21, 61, 178
so I match your counts until n = 5.
To help identify the cause of the discrepancy, let me ask this:
For n = 5 (5 segments) how many non-homeomorphic _connected_
compactifications did you get which cannot be represented with
less than 5 segments? I get 39 such spaces.
