Presentation

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

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

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