Presentation

minimal degreeμ(G) = 28
transitive degreeμt(G) = 128

A minimal faithful permutation representation — 6 generators on 28 points:

(2,4)(7,11)(9,12)(23,27)(26,28);(1,2)(3,4)(14,17)(15,19)(22,25)(23,27);(21,22)(23,26)(24,25)(27,28);(14,17)(18,20)(23,27)(26,28);(5,6,8,10)(7,9,11,12)(13,14,16,17)(15,18,19,20)(21,22)(23,26)(24,25)(27,28);(5,7)(6,9)(8,11)(10,12)(13,15,16,19)(14,18,17,20)(21,23,24,27)(22,26,25,28)

Polycyclic presentation:
