Presentation

minimal degreeμ(G) = 28
transitive degreeμt(G) = 64

A minimal faithful permutation representation — 7 generators on 28 points:

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