Presentation

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

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

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