Presentation

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

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

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