Question:Anybody has experience of calculating inverse for a complicate matrix

Maple
I'm working with inverse of a complicated matrix, which is 12*12, and all the elements are symbols. I included that matrix at the end. The program is running forever, no results, no error message? Anybody has such kind of experience, any suggestion that what I can do? Thanks a lot, I appreciate your help! Matrix([ [a+b+c+d+e,a+b+d+w*e,a+b+d+w^2*e,a+b+c,a+b,a+b,a+c,a, a,a+c,a,a], [a+b+d+w*e,a+b+c+d+e,a+b+d+w*e,a+b,a+b+c,a+b,a,a+c,a, a,a+c, a], [a+b+d+w^2*e,a+b+d+w*e,a+b+c+d+e,a+b,a+b,a+b+c,a,a,a+c,a, a,a+c], [a+b+c,a+b,a+b,a+b+c+d+e,a+b+d+w*e,a+b+d+w^2*e,a+c,a,a, a+c,a, a], [a+b,a+b+c,a+b,a+b+d+w*e,a+b+c+d+e,a+b+d+w*e,a,a+c,a,a, a+c, a], [a+b,a+b,a+b+c, a+b+d+w^2*e,a+b+d+w*e, a+b+c+d+e,a,a,a+c, a, a,a+c], [a+c, a,a,a+c,a, a,a+b+c+d+e,a+b+d+w*e,a+b+d+w^2*e, a+b+c, a+b,a+b], [a,a+c,a,a, a+c,a,a+b+d+w*e,a+b+c+d+e,a+b+d+w*e, a+b, a+b+c, a+b], [a,a, a+c,a, a, a+c, a+b+d+w^2*e,a+b+d+w*e,a+b+c+d+e, a+b,a+b,a+b+c], [a+c,a,a,a+c,a,a,a+b+c, a+b,a+b,a+b+c+d+e, a+b+d+w*e, a+b+d+w^2*e], [a, a+c,a,a,a+c,a,a+b,a+b+c, a+b, a+b+d+w*e, a+b+c+d+e, a+b+d+w*e], [a,a,a+c,a,a,a+c,a+b, a+b,a+b+c,a+b+d+w^2*e,a+b+d+w*e, a+b+c+d+e]]);
