Presentation

minimal degreeμ(G) = 20
transitive degreeμt(G) = 32

A minimal faithful permutation representation — 6 generators on 20 points:

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

Polycyclic presentation:
