Presentation

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

A minimal faithful permutation representation — 4 generators on 28 points:

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