Presentation

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

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

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