Yes, but I'm not sure I'm supposed to reproduce it here? Can I?
It's not difficult. Just practice 20m and 10m circles on both reins in trot and walk, trot-walk-trot transitions, free walk on the long rein you need to give enough rein to allow your horse to stretch as far as possible while keeping a consistent contact ie. don't just chuck down the reins and push him/her on to overtrack - double points for the free walk - and a nice square halt.
The most complicated it gets is a half 10m circle right at E to X followed by a half 10m circle left at X to B followed immediately by a transition to walk after B for 3-7 strides. The rest is just 20m circles and changing the rein across the diagonal.
