# Group Actions on Magic Squares

**Abstract.**
Two types of magic *n* times *n* squares are studied -
the * pandiagonal * squares and the *W*-squares, in which the coefficients
of all 2 times 2 submatrices have the same sum.
For n between 4 and 8 big groups - in general wreath products - are
described which act on sets of these magic squares.
