Did you realise there are 1820 ways to make connections of four American presidents from this grid

I could see assassinated - but couldn’t get them all

I thought there might have been a Sweeney connection which would have been clever Regan & Carter but it turns out you just spelled Reagan incorrectly

Mount Rushmore might have helped us non USA o files !

For me this was a grid that was too clever for its own good - with me spending too much time looking for a connection based on a misspelling

BTW - are you British as the flag on this grid implies or American as the flag on grids of the same name and contents of this grid imply ?

Very clever but so many possible connections and different possible groups that solutions to the grid that there are several valid solutions. Not sure having four groups of US presidents linked in different ways will result in a grid that has only one possible solution. Two of these groups mixed with other other groups would be great I got the assassinated group (but assassinated wasn't accepted as a link?), and the multiple presidents with the same name group - but I stumbled on the correct combinations by pure luck rather than logically excluding others. I was confused by Reagan being spelled Regan - so wasted the rest of my time, and my guesses for connections on non-president links.

Their is a typo in the list of answers, it's supposed to say William, not Woodrow.

I'm American but I accidentally pick british, also I know Reagan is mispelled.
