For a sequence $a_1, a_2, \ldots, a_n$, we define the exponent, tetration and pentation of a sequence $a_n$ as $\overset{n}{\underset{k = 1}{\textrm{E}}} (a_k) = a_1[3]a_2[3]\cdots[3]a_n$, $\overset{n}{\underset{k = 1}{\textrm{T}}} (a_k) = a_1[4]a_2[4]\cdots[4]a_n$, $\overset{n}{\underset{k = 1}{\mathrm{\Phi}}} (a_k) = a_1[5]a_2[5]\cdots[5]a_n$. Also, we define the $i$-th hyperoperation of a sequence $a_n$ as $\overset{n}{\underset{k = 1}{\textrm{H}_i}} (a_k) = a_1[i]a_2[i]\cdots[i]a_n$.

Super perfect magic square refers to a magic square with multiple changes and mutual conversion. In this paper, a construction method of magic square, called balancing method, is created, which can quickly construct even order super perfect magic square. The characteristic of this method is that the larger the order of magic square, the more selectivity, and the easier it is to construct.

in the construction of magic square, single even magic square is the most difficult. In this paper, we find a kind of super perfect magic square of order 6, which has a variety of dynamic change patterns and can be called a ten thousand square graph.
