Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 128

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

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