Conjectural modulo-11 congruences for overcolored partition k-tuples

Prove the conjectured modulo-11 congruences \(\bar{b}^8_{5,1}(22n+11)\), \(\bar{b}^4_{4,3}(22n+11)\), \(\bar{b}^5_{1,4}(22n+11)\), \(\bar{b}^{10}_{1,4}(22n+11)\), and \(\bar{b}^4_{4,1}(22n+11)\) vanish modulo 11 for all \(n\ge0\).

Background

The authors give five computationally supported congruences modulo 11 for the overcolored partition k-tuple coefficients. These statements are explicitly labeled conjectures and remain unproved in the paper.
