I Know that because the 1&6, 2&5, and 3&4 pistons move with each other up and down.
Ever notice that when seeing a block?

That means that:
1 & 6 have to be 3 after each other.
2 & 5 have to be 3 after each other.
3 & 4 have to be 3 after each other.

Also in the equation: No cylider ever fires after the one positioned next to it.

You can also get the firing order by looking at your cams and see what order the cams have their lobes stick out.
