Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 128

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

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