+--+--+--+ |2 | 6| 4| +--+--+--+ |2 | 0| 0| +--+--+--+The 2x3 grid given above has an interesting property: If you read horizontally, you get 264 and 200, where 264×200 = 52800. If you read vertically, you get 22, 60 and 40, where 22×60×40 = 52800.
So the horizontal product is the same as the vertical product. Find a 2×4 grid with the same property using 8 different digits.
