The three conjectural sporadics in the entropic order on a parabolic quotient of S6S_6

In the above notation, let the displayed arrays denote the corresponding elements of the parabolic quotient, and let \rhd denote the entropic partial order.

Three sporadic entropic-order conjectures. The following three relations hold:

3711:(acf\bde)(abd\fce),4311:(ade\bcf)(abd\fce),4911:(adf\bce)(abd\fce).\begin{array}{rcl} \mathbf{37}\rhd\mathbf{11}:\quad \left(\begin{array}{ccc}a & c & f\b & d & e\end{array}\right)&\rhd&\left(\begin{array}{ccc}a & b & d\f & c & e\end{array}\right),\\ \mathbf{43}\rhd\mathbf{11}:\quad \left(\begin{array}{ccc}a & d & e\b & c & f\end{array}\right)&\rhd&\left(\begin{array}{ccc}a & b & d\f & c & e\end{array}\right),\\ \mathbf{49}\rhd\mathbf{11}:\quad \left(\begin{array}{ccc}a & d & f\b & c & e\end{array}\right)&\rhd&\left(\begin{array}{ccc}a & b & d\f & c & e\end{array}\right). \end{array}

These are the remaining sporadic relations identified in the paper; the preceding discussion explains that the author was unable to prove them and that their structure does not yield to the techniques used for the other relations.
