Presentation

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

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

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