Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 512

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

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