Sam Lisi: At least in a mathematical context, I think "symmetric" is far more common. For one thing, there are many technical terms where "symmetric" is the correct choice (e.g. "symmetric space", "symmetric relation", "symmetric group"). I can't think of any technical term including "symmetrical".

Don't take anything it says as gospel or draw logical conclusions from it. Frankly the same could be said for the OED, but wiktionary is not written by people who have spent a long time judging such things.
