Presentation

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

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

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