Four cube-shaped dice have a different letter on each of their faces, so that between them they feature the first 24 letters of the alphabet, A to X, exactly once each.
I throw the four dice, and make a note of the four uppermost faces. I do this repeatedly, the results of which are shown below. Can you work out what letters are on each of the dice? The letters on one of the dice can be rearranged to form the surname of some famous brothers.
