Twisted Baxter permutation have a syntactically similar definition, being those that avoid 2-41-3 and 3-41-2. Call these larger sets counted by B(n) a set of Baxter objects of order n, and their subsets counted by Θk,ℓ a set of Baxter objects of order (k,ℓ).

Later, in 1978, Chung, Graham, Hoggatt, and Kleiman produced a remarkable …

Web18 sep. 2024 · Definition 0.2. An involution is an endomorphism \sigma whose composition with itself is the identity morphism: \sigma \circ \sigma \;=\; id\,. Such an endomorphism is necessarily an automorphism, being its own inverse. Involutions are equivalently the value on the single non-trivial element \sigma in \mathbb {Z}/2 of a group action by \mathbb ...
