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