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