Presentation

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

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

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