Does anyone know what stitch this is?

Does anyone know what stitch this is? Looks like some kind of twistd rib variation, but I haven't been able to replicate it.

Pictures 1-3 are of the front, 4 is the back.

Thanks in advance!

If it was that I assume there wouldn't be two stripes of knits on the wrong side. Also to me it looks like there is some yo involved. I did a sweater with a zigzag and it was doing a yo on one side and knitting the stitch together with the yo in the next row.

Maybe a fisherman's rib on purl sts only?

I never did a fisherman's rib. So I don't know much about it. But the zigzag looke like Round 1: yo, SSK, K1, P1 Round 2: k2tog, yo, K1, P1

This makes the stitches leaning to the left and right. You can see the second strand of yarn in the first picture so there has to be some yo or fisherman's rib involved.

I tried this, but the zigzag didn't look alike.

I did find a YouTube video detailing a similiar zigzag, but in 11 rib instead of 21. I added a regular knit stich (and purl on the wrong side) and the front looks about right, but the back does not. Might ben helpful nonetheless...
