Presentation

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

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

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