There is a 3x3 magic square (each row, each column and each main diagonal add to the same value), presented in a number base higher than ten but no higher than 36, so that A is a digit representing ten, B representing eleven, etc.

In this magic square, one of the cells contains what looks like the word DO (that's a letter O), which, by the rules, represents thirteen times whatever the base is, plus twenty-four.

Not only does the word DO appear as one of the numbers in the grid, but also the number representations in the bottom row, if concatenated together, form the word MAGIC.

What is this magic square?
