This surprised me: sage: M
[203 0 0] [300 250 0] [322 300 203] sage: type(M) <class 'sage.matrix.matrix.Matrix_dense_integer'> sage: L=M.columns()[0] sage: L (203, 300, 322) sage: type(L) <class 'sage.modules.free_module_element.FreeModuleElement_generic_dense'> How did we get from a matrix of integers to an element of a free module? I can understand this at one level, but this may be a bit too implicit. Justin -- Justin C.
