Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 128

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

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