Presentation

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

A minimal faithful permutation representation — 4 generators on 28 points:

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