I wanted to be a little more clear on this. The issues I ran into with the
3C and 4C pieces did not require undoing previous work (I could find
sequences to solve the pieces). So I am perhaps using the term "parity
problem" too loosely, but what I meant is that when 2 or 3 pieces were left,
their positions/orientations were in states that were very strange looking
compared to the 4^3.

On the 2C pieces, I think you can get yourself into more a genuine "parity
problem" if you don’t solve the 2C pieces along the rings first. And by
this I mean, you’d have to undo previous work to fix the issue…

All the best,
