h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

Isuggest that there can be no general rules for a game played in n dimensions.
tnough it may be possible to define rules for regular surfaces within any given multi-faceted shape.
angular borders present the greater difficulty, wheather to specify like or unlike symbol
oneither side of the cojoining angle. (should the rotating peak of a pyramid show "xxx" or "oxo"?).

What about for an n-dimensional hypercube?
There should be some generalisation there, and that was the main thrust of this problem.

i would have thought thst the minimal playable grid answer was three for any d?

although maybe i don't understand the question

btw, i once saw something on tv where someone made a noughts and crosses playing computer by using match boxes for each position in the game tree

the computer played randomly at first but if it lost a pebble was placed in the last box of its game (or something like this). thinking about it now i can't understand why match boxes were used instead of pencil and paper....

...perhaps i was drunk at the time

matrices would be useful for any calculations
