What about U D T T Q C S S H...? The same thing but in French (or spanish or portuguese...) But are the two sequences equivalent?   The immediate answer is NO. That's only if you consider the words to be distinct from each other- ultimately the words are just a way of discribing the same concept, independent of the language being used.     (that being said I really should read a paper that's been on my desk for years about the Worfian hypothesis before I venture that again).   IP Logged a shade of wit and the art of farce. towr wu::riddles Moderator Uberpuzzler Some people are average, some are just mean.     Gender: Posts: 13730 Re: what makes a sequence a sequence?   « Reply #1 on: Dec 8th, 2008, 12:34am » Quote Modify I'd say they're two different sequences with a one-to-one transformation between them.   There's also the issue that they're letter sequences, not concept sequences. You can't take the first letter of a concept, because they don't have letters. IP Logged Wikipedia, Google, Mathworld, Integer sequence DB Noke Lieu Uberpuzzler pen... paper... let's go!
