How to check if any pairs (or more) of entire columns are duplicates of each other

Trying to check if any permutations of entire columns (not row wise) match any other entire columns within columns H:Q of my dataset, inclusive. There are around 200,000 rows of data. Can't seem to figure this out myself, any help would be greatly appreciated!
