Presentation

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

A minimal faithful permutation representation — 4 generators on 28 points:

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