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