Presentation

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

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

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