Presentation

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

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

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