R3: (here the fun begins): k6, *k4, (p1, k5) twice, rep from * 4 times more, k6.
I believe you only do what is in the brackets twice then k4 and do what is between the brackets twice, etc. so it would look like this:
k6, k4, p1, k5, p1, k5, k4, p1, k5, p1, k5, k4, p1, k5, p2, k5, etc... till you get to the end and then k6 for the edge.
Someone will correct me if I'm wrong.
