Presentation

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

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

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