Presentation

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

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

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