Presentation

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

A minimal faithful permutation representation — 5 generators on 28 points:

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