Directions question

I’m knitting a small teddy bear. The directions were clear up until now working on the head. With 26 stiches on the needle direction for the next row says “On 23, k21, k2tog.” What do they mean by “On 23”?

Do they mean row 23? :??

Do you have a link to the pattern or at least a name?

It means ‘on/over 23 sts’ k21 of them and k2tog. That uses up the 23 sts.
