What is the shortest URL that can store the order of 78 items?

I'm trying to figure out how to have the shortest URL possible that stores the order of 78 cards. The best I could do was using 78 different characters, each representing a different card.

Is there a formula that could do a better job for开发者_如何学Go me?

Cheers,

You might try a compression format? It essentially will find patterns in your char data and group them.

For example: say your 78 char format has a 8273400000234270000 then you might see 827340r5234270r4 instead. It gets a lot more complex than that and I'm willing to bet there's much smoother/better solutions on the web. Here's a google search for String Compression.
