Presentation

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

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

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