Presentation

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

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

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