Presentation

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

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

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