Presentation

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

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

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