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