Regardless of how you choose your number sequence, buy two of the same sequence. If it's a split, you get twice the share.

  No, you don't. If it's a split with one other person, you get 2/3 instead of 1/2, that's only 33% more. If it's a split with two other people, that's 2/4 instead of 1/3, which is only 50% more. etc. and always less than twice as much. And in all the other cases where it's not a split (either you lose or you win alone), you paid twice as much.

    No you see, as the number of winners approaches infinity, the share does double. And goes to zero. So uh.

    Of course, you are correct.

  From the point of view of your investment (ie. a single ticket) you are guaranteed you will have to split (with the other ticket). You would do much better by buying two tickets with independent sequences, which is going to double your chance of winning.

  This really lowers your expected value by a lot What you describe is very very far from the optimal strategy.
