Handbook guide to measuring non-commutativity, structure-preserving maps, kernels, images and quotient-factorisation.
Computing a reduced basis of the integer kernel and image of a matrix, and why this is not the same as clearing denominators from a rational kernel.
Computing kernel and image bases for rectangular matrices over a field, and why the integer analogue is a different problem.
