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