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