Presentation

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

A minimal faithful permutation representation — 4 generators on 28 points:

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