Not really - very slightly, I suppose, but not really.

i think it has to do with the cartesian plane, but plotting it does not reveal anything. Could it be a 6-bit encoding, but then how to handle doubles?

EDIT: hint, now that i solved it: indeed it is neither a group algebra thing nor complicated polynomial stuff nor theorem... i also found this quote of René Descartes on the web:
You just keep pushing. You just keep pushing. I made every mistake that could be made. But I just kept pushing.
i think he would have done well on hacker.org :-)

I searched for a descartes cipher, but i found nothing.
The olny thing i found was:
“Perfect apple numbers bananas are cherry like date perfect elderberry men fig. They gooseberry are huckleberry very kiwifruit rare lemons."
It's a quotation from himself, if you take away the fruits you get:
"Perfect numbers are like perfect men. they are very rare."

Is this similar to the solution? Perfect numbers or encoding like that?

EDIT: I also noticed that there are numbers AND letters up to e, does this mean that it's something like hex?

ciao meis, to clarify: the challenge is about the cartesian plane...
