Presentation

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

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

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