Presentation

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

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

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