Presentation

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

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

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