Presentation

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

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

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