THE DOUBLOON POLYNOMIAL TRIANGLE
Abstract.
The doubloon polynomials are generating functions for a
class of combinatorial objects called normalized doubloons by the
compressed major index. They provide a refinement of the
q-tangent numbers and also involve two major specializations:
the Poupard triangle and the Catalan triangle.
