I don't like the diagonals. They are not "mathematical" .
If we use diagonals, then I would like to use all 24 diagonals
with the board on a torus

can't you make the participants to do it by themselves ?

yes, maybe we should make it public so everybody can join ?
JC will hopefully ban the spammers

did Fei Lu join ?

oops, OK. I see. So not open to everybody. We're still having secrets
at this point ;-)

this is an interesting field to fight the battle of human ingenuity
as demonstrated on Jelliss' pages vs. brute force computer power
as in JC's program !

Well, the computers _must_ win one day, since they are much faster.
But implementing complicated and intelligent algorithms to perform
the tasks could be more difficult than to prove or search directly
by human power !

On the other hand current computer calculations seem pretty useless
on a historic scale as long as computers are getting ever faster.
Just waiting 2 years halfs the effort ! And what's two years compared
to the timescale of magic knight tour's history.

Probably a cooperation human+computer is most promising :
Design some partial-tour and the check by computer whether it can be
completed.

... and make an entry in Sloane's EIS :
0,0,0,0,0,0,0,140,0,0,0, (numer of SMKTs on an n*n-board)

what about 3 dimensional-tours BTW. ?
