Presentation

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

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

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