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