Presentation

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

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

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