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