Presentation

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

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

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