Presentation

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

A minimal faithful permutation representation — 5 generators on 28 points:

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