I think this must be a translation because it's written a little oddly. Here's how I see it -
Knit for 31 rows
Pick up 15 stitches on the small end
Pick up 41 stitches on the next side
Pick up 15 stitches on the next side
You now have 112 stitches on your needles.
Join and continue pattern. (you'll be knitting in the round)
