Presentation

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

A minimal faithful permutation representation — 6 generators on 28 points:

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