You're of course right that it's only for meaningful positions. I'm not sure it invalidates my claim, but maybe it does. I would argue that to a cuber, all cube positions are meaningful. Just the fact that they're random doesn't mean they're hard to memorize/recognize. But maybe it is somehow fundamentally a much bigger harder problem in some way. It would be interesting to know how the number of possible "meaningful" chess positions compares to the number of possible cube positions. Not that that conclusively proves anything, but it's an indicator. On Mar 1, 2006, at 7:59, Stefan Pochmann wrote: > Do you remember a place where I could read about these results?

Are there any other comparable cases of instant recognition that people do? I haven't had my coffee, so I can't think of any. I'm thinking less of conscious memorizing of symbols and more about things that plugs into our instinctive abilities. That's often thousand of times faster. - - - - - - - - - - - - "The power of accurate observation is commonly called cynicism by those who have not got it." -- George Bernard Shaw Lars Petrus - [EMAIL PROTECTED] http://lar5.com Yahoo!
