Sage uses different algorithms based on difficulty. http://git.sagemath.org/sage.git/tree/src/sage/matrix/matrix_integer_dense.pyx#n3252 I'm guessing in this case it's this branch: http://git.sagemath.org/sage.git/tree/src/sage/matrix/matrix_integer_dense_hnf.py#n184 -- harald -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
