Stellated color code[1]
Description
A non-CSS color code on a lattice patch with a single twist defect at the center of the patch.
Rate
Stellated color codes have negative curvature around the central defect, and thus circumvent the BPT bound for codes on Euclidean lattices.

- Triangular surface code — Stellated color codes are color-code analogues of triangle surface codes in that both encode logical information in lattices with a single twist defect. Instances of the former can be obtained by fattening [2] the vertices of the latter [1].
