My thoughts exactly. Also, there are enough additional permutation rules to balloon the result space way beyond the reach of even a modest super computer.
One approach would be to lease a massive cluster of cloud computers to carry out the calculations. However, this option isn't financially viable for a lone developer.
Maybe there's an alternative way of approaching the problem.
The potential for case changes in the words really makes the keyspace much larger, since we currently don't know the length of the words.
