• Doubloon polynomial triangle
• Poupard triangle
• Catalan triangle
• Reduced tangent numbers

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.
