Presentation

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

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

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