cheers, i have already read this paper but unfortunately it does not deal with the BCH as a commutator expansion (nor does the mathworld page, incidentally)... and for high orders it is a very difficult job to collect the commutator terms. i was able to implement the above which was able to practically work to about 20 orders in [another CAS]. i guess i'll just have to do the same in mathematica and hope that someone has written a Commutator package
