A magic square is a square matrix containing numbers such that the sum of any row, column, or diagonal is the same[1][2]. A magic square using the sequential numbers 1..n where n is the number of cells is called a normal magic square. Magic squares are believed to have been discovered in China about 4th century BCE. The 3x3 normal magic square was called 'Lo Shu' by the Chinese. Magic squares were known in ancient Egypt, India, and Arabia.
