Presentation

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

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

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