Are there "laws of the cube", a bit like boolean algebra laws (I simply boolean expressions as well), such as certain sets of moves, four or so in length, that cancel down? I know simple things like RU2R' twice in a row cancels down to nothing, or that RUB'U'R'U=B', but is there more? I would like to know, because I've got a couple of really long algs that I want to reduce to their simplest form.

P.S. I know this forum is not for speedcubing, but of course the main reason why I want this is to save time !
