I want to repeat the quadratic bezier around these points on a circle as annotated in the blender file.

I have tried modulo with index with transfer attribute but I get red wires.

I am unable to upload a picture. Error with the server. I have uploaded the blender file. Blender 3.3.1

You need to first spawn multiple beziers, then assign the averaged position as the handles (actually it's not an averaged position, just a sum in your case). Unfortunately, those beziers are cubic; if you really care about quadratic beziers you can ask either how to manually create a polyline to fit a quadratic bezier, or how to position cubic bezier handles so that they are equivalent to a quadratic bezier...

This version constructs the inner circle and the petal quadratics at the same time, which saves a few nodes, fiddling with control-points for each circle-side? It just has to do the trig. once to figure out where the circle-corners are on the max Y side, and then it rotates instances of the petal into place:

Parameters permit changing number of sides, inner/outer radius:

It would be up to you to further embellish the circle, convert all to mesh, etc.
