The self-conjugate consecutive-core and symmetric generalized Dyck path conjecture

From papers

Let ss and kk be positive integers. A self-conjugate (s,s+1,,s+k)(s,s+1,\dots,s+k)-core is a self-conjugate partition that is simultaneously an ss-core, (s+1)(s+1)-core, and so on through an (s+k)(s+k)-core. A symmetric (s,k)(s,k)-generalized Dyck path is a generalized Dyck path with parameters (s,k)(s,k) that is invariant under the relevant reflection symmetry. Self-conjugate consecutive-core conjecture. The number of self-conjugate (s,s+1,,s+k)(s,s+1,\dots,s+k)-cores is equal to the number of symmetric (s,k)(s,k)-generalized Dyck paths. This extends the proved case of three consecutive core parameters established earlier in the paper; the conjecture proposes the corresponding equality for every pair of positive integers ss and kk.
