Presentation

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

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

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