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