Presentation

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

A minimal faithful permutation representation — 3 generators on 28 points:

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