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