Presentation

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

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

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