Presentation

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

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

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