Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 64

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

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