Paul Raican reports an accurate(and I assume unique!) hs#4 solution:

So, the stipulation can be changed to hs#4**.

No, Shankar, actually I found a set play in 3 moves.

Sorry, Paul!
You’re right. The move numbering confused me.
So, it’s actually a hs#3.5 with 2 solutions and 1 set play: 0.0.1.1.1.1.1.1 + 0.2.1.1.1.1.1.1

Maybe the numbering in such cases should be like:
2.Rf7+ rDGg8 3.b6 rDGa6 4.Rc7+ Rxb6(Rb6→h8)#
1…Rb3 2.Re7 rDGf8 3.b6 rDGa6 4.Rc7+ Rxb6
(Rb6→h8)#
1…Rf2+ 2.rDGg1 Rf8 3.Rc7 rDGd8 4.Rc8+ Rf1#

This set play could also work as a 3rd solution, if “stationary moves” are allowed!:
1…rDGb1-b1! 2.Rf7+ rDGg8 3.b6 rDGa6 4.Rc7+ Rxb6(Rb6→h8)#

Maybe Peter *did* notice this set play but decided not to indicate it.

Set play is virtually the same as the first solution, so it doesn’t add a thing.
