Help with pattern

Hello, I need help with this pattern, here it is.
Ch4, 1dc between dc, ch4, * 1 gr in ch1 sp, ch4, rep from * 34 times more, 1 gr in ch1 sp, turn.
What I don't understand is * 34 times more, do I do another group in ch1 space or not before I turn?
Hoping someone can make this clear for me
