Confusion on Sweater pattern
Can anyone tell me what this means in this pattern?
On next round, begin the following pattern and repeat within brackets 5[4,0,0,0] times:
[R1: K from beginning of round to 1st marker, slip marker, K1, YO, K to one before 2nd
marker, YO, K1, slip marker, K to 3rd marker, slip marker, K1, YO, K to one before end
of round, YO, K1.
R2: K around in St st.]
I understand the actual pattern, but the part that confuses me is the first part stating repeat within brackets 5 (4, 0,0,0) times?
I haven't started the pattern yet, since I want to make sure I am capable of reading it first!
