Presentation

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

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

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