Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 512

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

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