Better than what?

In gridchecker I have several good UA finders that served well for my experiments.
(Most code is in grid.cpp and uset.cpp)

For a task close to your, once I generated ~10M UA for SF grid. Attempts to find symmetries/asymmetries failed. Partially due to lack of knowledge how to test the null hypothesis.

Fair point. I haven't really looked at those yet … I assumed perhaps they were most likely geared towards the low size end, eg for use with hitting sets/low clue puzzle search etc …
