what is wrong with the eigenspaces method here? thank you for your help
MS=MatrixSpace(GF(2),16,16) A=MS([ [1,0,1,1,0,0,0,1,0,0,0,0,0,0,0,1], [1,0,0,0,1,1,0,1,1,0,0,0,0,0,0,0], [0,1,0,0,1,1,1,0,0,1,0,0,0,0,0,0], [0,0,1,0,0,1,1,1,0,0,1,0,0,0,0,0], [0,0,0,1,1,0,1,1,0,0,0,1,0,0,0,0], [0,0,0,0,1,0,0,0,1,1,0,1,1,0,0,0], [0,0,0,0,0,1,0,0,1,1,1,0,0,1,0,0], [0,0,0,0,0,0,1,0,0,1,1,1,0,0,1,0], [0,0,0,0,0,0,0,1,1,0,1,1,0,0,0,1], [1,0,0,0,0,0,0,0,1,0,0,0,1,1,0,1], [0,1,0,0,0,0,0,0,0,1,0,0,1,1,1,0], [0,0,1,0,0,0,0,0,0,0,1,0,0,1,1,1], [0,0,0,1,0,0,0,0,0,0,0,1,1,0,1,1]])
p=A.charpoly()
p.factor()
