He he he, I'll never tell.

Actually:

#include <conio.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <time.h>

#define LEN 6

int main (void)
{
    char str [LEN + 1]  = "123451";

    unsigned long *list = NULL;

    int  count = 0;

    srand ((unsigned) time (NULL));

    while (!kbhit ())
    {
        int    i, found = 0;
        unsigned long x;

        for (i = 0; i < LEN; i++)
        {
            char temp = str [i];
            int  rnd  = rand () % LEN;

            str [i] = str [rnd];
            str [rnd] = temp;
        }

        x = strtoul (str, NULL, 10);

        for (i = 0; i < count; i++)
            found = found || list [i] == x;

        if (!found && x % 2)
        {
            list = realloc (list, (unsigned long) (count + 1)
                * sizeof (unsigned long));

            if (!list)
            {
                puts ("\n\nOut of memory!\n\n");
                return EXIT_FAILURE;
            }

            list [count++] = x;

            fprintf (stderr, "\b\b\b\b\b");
            printf  ("%s ", str);
            fflush  (stdout);

            if (count % (60 / (LEN + 1)) == 0)
                putchar ('\n');

            fprintf (stderr, "%05d", count);
        }
    }

    if (!getch ()) getch ();

    fputs  ("\b\b\b\b\b     \b\b\b\b\b", stderr);
    printf ("%s\nFinal count: %d\n", count % (74 / (LEN + 1)) ? "\n" :
"", count);

    return 0;
}

It's probably even more brute force than any one imagined. :-)  Except
for the kbhit() and getch() calls, it's standard C.
