Presentation

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

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

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