Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

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

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