01:16:20 <jeffro256[m]> @UkoeHB the methods wallet2::get_multisig_seed() and wallet2::restore() (the multisig overload), haven't been touched in 5 years and do not store/load the field m_multisig_derivations. I might be wrong, but it's probably necessary to use this field to restore multisig wallets from scratch (and skip the initial key exchange / preparation stages), yeah?

01:39:33 <jeffro256[m]> Nvm it seems the derivations aren't needed after finalization
03:18:52 <UkoeHB> jeffro256[m]: right
03:20:02 <jeffro256[m]> How many multisig private keys should there be given M/N?
03:25:07 <jeffro256[m]> (after setup)
06:41:44 <jeffro256[m]> Koe could you pretty please double check that https://github.com/monero-project/monero/pull/8914 is correct?
12:16:50 <UkoeHB> jeffro256[m]: one for every group of size N - M + 1
12:40:27 <UkoeHB> so I guess N choose (N - M + 1) would do it (there is n choose k in seraphis_lib src/seraphis_crypto/math_utils.h)
