what about this square, it does not have an inverse

1 1 1 1 1 1 1 1 1

was about to fall asleep but then PROPOSITION:

  • all magic squares are constant multitles (all numbers multiplied by a certain value), or shifted (all numbers added to by a certain value) of a very few variations of “base” magic squares this seems intuitively true by a sleepy deprived person at 1am, but if we can prove for these “base” squares, would that be the way to prove for the general case?

i.e. there r and infinite number of 1x1 magic squares, but there is only one case to deal with if we want to prove anytning about it
