Matrix Permutations

Hello,

how do I get all permutations of a Matrix?

For the following exercise I would like to get all permutations of a Matrix with integer values in the range 0 to 9. There should be 104 permutations. And then generate the permutations of tuples with three matrices. 1012 permutations and then I would filter the list somehow for the invertible matrices.

Is there a better way?

Exercise: Let S,T,UR2x2 such that, Si,j,Ti,j,Ui,j0,1,,9 How many of the products STU are invertible?

In the Sage reference for permutation I couldn't find any thing.

Thanks

PS: The curly braces couldn't be escaped properly in the LaTex part ... \{0,1, \cdots, 9\}
