I don’t mean to assert that a solution is computer-assisted simply
because the puzzle is implemented in software. In the case of MC4D the
most obvious forms of assistance are undo/redo and the macro facilities.
The piece finding tool in Magic120Cell is another obvious computer aid.
I also consider the reset command to be a computer aid. You can see how
intelligent minds can begin to disagree about just what constitutes an
aid and the degree to which those aids should or should not matter when
comparing solutions.

I’ll continue to maintain the existing record categories in the HOF but
please feel free to create and curate any new categories on the wiki
that you feel motivated to maintain.

Congratulations on your amazingly short solution BTW,
