Abstract
The so-called Entringer–Poupard matrices naturally occur when the distribution of the statistical pair (“last letter”, “greater neighbor of maximum”) is under study on the set of alternating permutations. They also provide a matrix refinement of the tangent/secant numbers. Moreover, their generating function can be explicitly derived.
