thank you guys.
alg.cubing expand/simplify works great on [:,] symbols, but r moves stay as r moves so cube explorer cant handle them.
and
algtrans.html is good but i need to manually do the manipulate convertion.
i think i have a new idea i will try to modify cubeexplorer512 code so it can automatically change r r' f' f moves to the supported moves. if all goes well i will try to modify cubeexplorer code so it can understand alg.cubing [:,] symbols. (i dont understand [:,] yet so i will have to study it, and it will work even when you are offline.
