@edwinbrady yes, it's the allowed routing. iirc, * is sequencing and / is alternation - 1 more reply

@edwinbrady It tells you what routes you are allowed to take. Slashes mean alternatives, asterisks sequential composition. -
@larsr_h I decided it was probably a logical formula, yes :). I'm wondering about relation to the price. Determined by the exact route? - 2 more replies
