Presentation

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

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

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