I got inspirations from https://github.com/LingDong-/magic-square-poems .
"Observe the above 5x5 matrix of Chinese characters: when read horizontally, it consists of five lines from five different poems, and so does it when read vertically, of the exact same lines. "
I prefer symmetric matrix but not magic matrix, because I think it's a symmetric matrix. Observe that when a matrix is symmetric, as in these cases, the matrix is equal to its transpose.
To solve this problem, I implemented a quicker parallel alogorithm. It only takes 36 seconds to find the symmetric poems.
