Presentation

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

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

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