%I A345679 #14 Aug 25 2021 21:41:17 %S A345679 1,12,8784,1031049216 %N A345679 a(n) is the number of disjoint preference profiles in the stable marriage problem with n men and n women. %C A345679 A disjoint profile is defined as a preference profile where each pair of rankings appears exactly once. %C A345679 A preference profile corresponds to a digit in a complete n^2 X n^2 Sudoku grid. %C A345679 A disjoint profile corresponds to a digit in a disjoint-groups Sudoku. %H A345679 Matvey Borodin, Eric Chen, Aidan Duncan, Tanya Khovanova, Boyan Litchev, Jiahe Liu, Veronika Moroz, Matthew Qian, Rohith Raghavan, Garima Rastogi, and Michael Voigt, <a href="https://arxiv.org/abs/2108.02654">The Stable Matching Problem and Sudoku</a>, arXiv:2108.02654 [math.HO], 2021. %e A345679 For n=2, there are 16 preference profiles. Each profile is either a disjoint profile or a joint profile. The number of joint profiles is A344693(2) = 4. Thus, the number of disjoint profiles is 12. %Y A345679 Cf.
