Best I could get is also 86850. Used a simple genetic algorithm - mutate using crossover points, exchange, reverse, and a bit of shuffling. Then cull all the losers and repeat. Quite ruthless really. First time I have tried this approach, seems very powerful.

Update: Sorry BrowserUK, I updated it within about 20 seconds of posting, you are indeed quick off the mark.
