Presentation

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

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

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