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