  1. Here, δk > 0 and states separated by commas are degenerate. The couplings in the microscopic basis, used in Fig. 4 for the respective orders, are listed under \({\bar{\lambda }}^{j}\). Except for SLP−, the leading superconducting states for λj and \({\bar{\lambda }}^{j}\) are the same (cf. Fig. 4 and Supplementary Appendix D1).
