Four Corner Magic Squares 6Í6 with semi Symmetric Center 2Í2

Abstract

      In this paper, we consider one type of the classical magic squares 6×6 having the four corner property, namely the Magic Squares with 2×2  Semi Symmetric Center, We list counting of this type and some of their algebraic properties. We present the general form of this type. We classified these sets of squares according to their eigenvalues and determinant, We give an example to each class in our classification, In each example we give the basis of the nullspase of the square as well as the eigenvalues and the determinant of this square.

      Our calculations and proofs are based on applying the theorems and methods of a linear algebra and computer programs, specially designed for matrix calculations
