Presentation

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

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

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