Presentation

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

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

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