    • tot than the d+id wave, for finite systems. Checking the system-size dependence (L = 4, 6, 12 and 18), however, we have found the values of the two symmetries seem degenerate in the L → ∞ limit. In reality, an antiferromagnetism with 120° structure, which is outside the scope of this study, is realized at δ = 0. We believe this Néel structure immediately breaks as carriers are doped, due to the substantial frustration.
