Presentation

minimal degreeμ(G) = 23
transitive degreeμt(G) = 192

A minimal faithful permutation representation — 4 generators on 23 points:

(5,8,9,18)(6,11,12,17)(7,14,16,15)(10,20,19,13)(21,22,23);(1,2,3,4)(10,19)(14,15);(2,4)(5,7)(6,10,12,19)(8,15,18,14)(9,16)(11,13)(17,20)(22,23);(2,4)(5,6)(7,13,16,20)(8,17)(9,12)(10,15,19,14)(11,18)

Polycyclic presentation:
