This is going to be a hard job. The number of permutations of the numbers 1 through 75 is 75! (seventy five factorial). This is a huge number. Not quite as large as 75 to the power 75, but still huge. This number is much larger than the number of gains of sand in all the beaches of the world. In short this job is impossible.
