It can get worse though... :-)

#include <stdio.h>

int main( void )
{
    for( int nn=0; nn<4096; nn++ )
        if( (nn & (nn >> 6)) == 0 ) {
            for( int empty=0, sq=0; sq < 64 || printf( empty ? "%d w - - 0 1\n"
: " w - - %d 1\n", empty ) == 0; sq++ ) {
                if( (sq % 8) == 0 || sq == (nn & 0x3F) || sq == (nn >> 6) ) {
                    printf( empty ? "%d%s%s" : "%*s%s", empty, "", sq && (sq %
8) == 0 ? "/" : "" );
                    empty = -printf( "%s", sq == (nn & 0x3F) ? "n" : sq == (nn
>> 6) ? "N" : "" );
                }
                empty++;
            }
        }

    return 0;
}
