Presentation

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

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

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