Unfortunately, as of the 0.3 release of Julian, this code can not be used to address the StackOverflow question. Although many of Julia's permutation built-in functions support large permutations, <tt>nthperm(p)</tt> is limited to partitions of no more than 20 objects. <tt>p = randperm(114)</tt> works fine, but <tt>nthperm(p)</tt> throws an <tt>OverflowError</tt>. Arguably, this is a bug, and it may be rectified in future releases.
