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