Magic squares prime order
Produces magic squares of prime order using the standard method
magic.prime(n,i=2,j=3)
n |
The order of the square |
i |
row number of increment |
j |
column number of increment |
Claimed to work for prime order, but I've tried it (with the defaults
for i and j) for many composite integers of the
form 6n+1 and 6n-1 and found no exceptions;
indeed, they all seem to be panmagic. It is not clear to me
when the process works and when it doesn't.
