Most-perfect pandiagonal magic squares and their Moore-Penrose inverse. (English)
Int. J. Math. Educ. Sci. Technol. 35, No. 5, 697-701 (2004).
In this note $(4\times4)$ most-perfect pandiagonal magic squares are considered in which rows, columns and the two main, along with the broken, diagonals add up to the same sum. It is shown that the Moore-Penrose inverse of these squares has the same magic property.
