Presentation

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

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

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