Presentation

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

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

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