Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

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

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