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