there won't be any current through them right? so we can just remove them. Is that wrong ?

I don't think that you can assume that there will be no current through them.

Sure. I've only labeled some of the resistances, the rest should be obvious by color code and symmetry.

Did you get 17R/16?

Nope. A bit too small.

Here's the next step in the simplification. The diagram is still symmetrical, so the Delta-Y transformations at either end will be the same...

Yup. That's what I had & did.

I got it - 23R/20
Thanks!

Yes, that's it. Attached is the summary of the simplifications used.
