Presentation

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

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

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