Of course it should have been "academic institution" instead of "academic institute". Bigtone53 is perfectly right they're slightly different and I am the one at fault for this mistake. I'll correct it above. Thanks!
I never regard symmetry has anything to do with a sudoku being "nice" so I don't suppose you need to delve into that idea too much.

You've over-estimated me.
