Presentation

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

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

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