Presentation

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

A minimal faithful permutation representation — 5 generators on 28 points:

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