Summary: Pfaffians are less familiar functions on skew-symmetric matrices, and yet Donald Knuth claims they are more fundamental than determinants. We explore connections between determinants and Pfaffians. Along the way, the reader will encounter combinatorial proofs of identities for both matrix functions and play with permutations, matchings, Reidemeister moves, and game theory.
