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