Revolving Double Century Puzzle

The Revolving Double Century has two puzzles in one and the harder of the two is exceptionally difficult!

The aim is to rotate the discs so every column adds up to 100 at the same time. You can take each disc off the stand and on one side there are six columns. This is relatively challenging with only 1 solution and 7,700 permutations. 

Flip over to the other side and there are twelve columns, meaning the difficulty rises considerably. Again there is only one possible solution but now there are 248,00 possible permutations!
