Comments

An alphamagic square is magic square for which the number of letters in the word for each number generates another magic square. This definition depends, of course, on the language being used. In English, for example, the magic square which is, by rows, (4, 9, 8; 11, 7, 3; 6, 5, 10) corresponds to the number of letters in: (five, twenty-two, eighteen; twenty-eight, fifteen, two; twelve, eight, twenty-five).
