Presentation

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

A minimal faithful permutation representation — 3 generators on 28 points:

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