Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 5 generators on 28 points:

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